| ▲ | ryanjshaw 5 hours ago | parent | prev [-] | | They could have made another $5 per 10 pizzas after order #1 by just delivering the pizza to themselves and sending the same boxes back out in the next delivery, and so on. | | |
| ▲ | mattmaroon 2 hours ago | parent | next [-] | | An actual DoorDash driver had to do the delivery though. So you risk being reported and also, if they take awhile, pizza gets cold. But they also could have just raised prices on everything but the cheap one DoorDash was using for pricing. | |

| ▲ | wizzwizz4 8 hours ago | parent | prev [-] | | If you want to fight the VCs, you have to pull stunts like this. If they want to destroy local infrastructure because "free market", in an attempt to secure monopolies for themselves, then let them operate in a free market. | | |
| ▲ | mattmaroon 2 hours ago | parent | next [-] | | But why do you think they’re harming “local infrastructure”? The food delivery services didn’t hurt anything but their investors in the end. And they kept the restaurant industry alive during the pandemic, the fallout would have been so much worse. I work in the industry and know several bar/restaurant owners who will tell you DoorDash and competitors are the only reason they made it through 2020-21. Early on they stopped prohibiting restaurants from upcharging, so restaurants all did. They ended up with some extra sales and profits. The customer got VC funded free delivery. Enough alternatives kept the market place efficient. DoorDash can’t get too abusive when UberEats and Instacart are competing, restaurants have no switching cost. The whole thing worked for basically everyone involved except maybe the investors (DoorDash has significantly underperformed the S&P since it debuted on the market.) | | |
| ▲ | BobbyTables2 8 minutes ago | parent | next [-] | | DoorDash finds a way to consistently screw up orders. Order A,B,C - receive only A+B, or A,B,D. No explanation. Tipped generously. For a long time, I myself drove and picked up my orders. The same restaurants rarely made mistakes. I never had to ask for missing item to be included. They always had everything in the bag. It’s happened so often, it has to be malice from one of the parties involved. | |
| ▲ | horsawlarway an hour ago | parent | prev [-] | | This has not been my experience. From my side, as someone old enough to remember Domino's running the "there in thirty minutes or it's free" promotions... These delivery services absolutely tanked the quality of delivery. Now you can basically only get slow delivery of over priced, cold food. Sure, you can get it from far more places, but it's a pyrrhic victory if I've ever seen one. Used to be if a restaurant offered delivery, it was ok food for delivery, at ok prices, and their drivers had gear to keep it warm and presentable. Now we basically only do pick up because these universal delivery companies suck at the one fucking thing they're supposed to do. But they've run all the local restaurants out of the delivery game. |

| ▲ | PaulDavisThe1st 6 hours ago | parent | prev | next [-] | | > then let them operate in a free market. I think you meant to say "operate in a market that is regulated in precisely the way they want it to be". | | |
| ▲ | wizzwizz4 4 hours ago | parent [-] | | I said what I meant: most VC-backed startups could not survive in a real-world environment. Thank you for highlighting the distinction. Note that a free market isn't necessarily an unregulated market (see: Adam Smith). Personally, I don't believe that free markets are a sensible way to manage local affairs. They work well on a medium scale, where goods are fungible and efficiency matters: but for something like the local pizza place, customer behaviour doesn't match that of a market participant. I don't think it's sensible to expect the local pizza place to be free of arbitrage opportunities. Someone who identifies and exploits such opportunities (e.g. "free meals available on request") would be taking advantage of goodwill, and the reason we can't have nice things. However, if a large corpo comes along and starts trying to undercut the locals, absolutely mug them for all they're worth: they're playing a different game, and it's not one you should want them to win. | | |
| ▲ | pdonis an hour ago | parent [-] | | > for something like the local pizza place, customer behaviour doesn't match that of a market participant. I'm not sure why you think that. "Market participant" doesn't mean "always takes the lowest priced deal". People are willing to pay higher prices for food from local restaurants, as opposed to chains, fast food, etc., because they feel that the extra value they are getting (better quality, knowing the people who make the food, the atmosphere of the restaurant, etc.) is worth it. That's a free market. What is not a free market is large corporations who get all kinds of government favors to prop them up coming in and taking advantage of arbitrage opportunities that the locals don't have the time or the energy to protect against--still more if such opportunities involve "marketing" the locals' products in ways the locals didn't agree to, and would not agree to if they were given the opportunity to make a choice. I completely agree with you that such things should be shut down. |

| I feel I should point out that USPS has a lower rate for postcards (currently $0.61), so the threshold might be a bit lower. I know that this is tongue-in-cheek and would be pretty funny to receive, but it isn't an apples-to-apples comparison. The experience of getting a little message printed on receipt paper is nothing like the experience of receiving a note or card in the mail. Through the mail you receive something physically from someone with their handwriting and some personality to it. Getting the Amazon message is more like printing out a text message on crummy paper. Also, I don't have Prime, so it definitely isn't cost competitive for me anyway. |

| ▲ | hatthew 8 hours ago | parent | next [-] | | I agree in general, but as a one-off thing I'd very much enjoy getting a lime with a message saying "this was cheaper than sending a letter myself" | | |
| ▲ | hoistbypetard 6 hours ago | parent [-] | | I've started sending paperbacks instead of greeting cards when someone I know needs a get-well-soon card. In stores around here, greeting cards are often $7ish + postage. I can frequently ship a paperback with a gift receipt for $5 total. I include a gift message on the gift receipt, and choose a book I think someone might like to read while they're out of commission. I guess it's a bit like postal arbitrage, if I accept the cost of greeting cards themselves as part of the cost of the activity. To the extent that anyone has commented much, those who have commented had very positive reactions to what amounts to a book recommendation and a copy of the book I'm recommending along with a little note. |

| Ah, luckily the climate doesn't mind that oil was extracted, a phone case was produced out of it, shipped from China, to end up not even being used but just as a "greeting card". Why yes, I am fun at parties. |

| ▲ | shagie 8 hours ago | parent | next [-] | | https://climate.mit.edu/explainers/freight-transportation > While nearly three-quarters of the world’s cargo is carried by ocean-going ships, road vehicles like trucks and vans make up the majority, 65%, of freight’s emissions. Most ships burn fossil fuels and emit carbon, but they carry large amounts of freight at the same time, making them the most efficient way to move cargo. Road freight, however, can emit more than 100 times as much CO2 as ships to carry the same amount of freight the same distance. Road transport is also a fast-growing sector—80% of the global increase in diesel consumption can be attributed to trucks. E-commerce and home delivery are two reasons for this growth. | | |
| ▲ | BobbyTables2 4 minutes ago | parent [-] | | Not disagreeing but it’s amazing a ship plowing water out of the way is so much more efficient. Perhaps trains beat road transport efficiency to a similar degree. |
| |
| ▲ | OrderlyTiamat 7 hours ago | parent | prev | next [-] | | The distance the boat has to cover is 11800 kilometers, and the truck covers only 54 kilometers. Taking that average of 12 times more usage from the table of sibling comment means the ship is still 20x worse. | | |
| ▲ | BrenBarn 7 hours ago | parent [-] | | But what if you apportion the fuel usage over the items transported? Presumably the ship carries far more items than the truck. | | |
| |
| ▲ | cinnamonteal 8 hours ago | parent | prev | next [-] | | The distance from Shenzhen to Long Beach is some 300 times the distance from Long Beach to Pasadena, depending on where exactly in Pasadena and which route you take. The CO2 emissions factor for a truck is some 10-100x that of a container ship. The exact ratio depends on what kind of truck, and what scope of emissions are being included. The more one accounts for, the more it will favor the boat. But overall, the emissions from the oceanic leg of the trip are probably anywhere from 1-3x those of the truck. | | |

| |
| ▲ | hi-wintermute 8 hours ago | parent | prev [-] | | I did some napkin math on this as I recently picked up a 3D Printer and wondered the environmental comparison to print-at-home vs pick something up at the store and I was surprised. Had some help from Claude but "last mile delivery" is absolutely where the majority of the kWh is burned in the supply chain. Container ships use ~0.015 kWh per ton-km[1] and a car is ~1.35 kWh/km. If you go to the store and end up getting >10 things it becomes "worth it" from an energy standpoint. Anything less printing at home seemed to be more economical... Not an expert though just saying it opened my eyes to how inefficient "last mile delivery" energy consumption is. [1] https://www.withouthotair.com/c15/page_95.shtml (old reference) | | |
| ▲ | shagie 7 hours ago | parent [-] | | > Not an expert though just saying it opened my eyes to how inefficient "last mile delivery" energy consumption is. One of the oddities of home shopping and delivery is that it can be more efficient. https://www.npr.org/2024/09/10/nx-s1-5020321/food-delivery-m... > In 2022, researchers from the University of Michigan and Ford Motor Co. modeled a single 36-item grocery cart to compare greenhouse emissions from an e-commerce grocery delivery and a traditional trip to the store to get the same items. Gregory Keoleian and colleagues at the university's Center for Sustainable Systems found that using an electric vehicle to pick up groceries could cut emissions by as much as half, compared to a gas-powered vehicle. > They also found that home delivery could be an even better option. That's because with a delivery vehicle, orders are often clustered, with a driver dropping off not just your groceries, but also hitting neighbors during the same run. "Delivery is actually going to be more efficient in general than driving yourself in a gasoline SUV to the store to pick up your groceries," Keoleian says. The mentioned paper is https://css.umich.edu/publications/research-publications/car... --- https://www.epa.gov/greenvehicles/what-if-more-people-bought... > A recent USDA survey found that in 88% of U.S households, people hop in their car to buy groceries, driving an average of 4 miles to their preferred store. ... All these car trips result in carbon pollution: over 17 million metric tons of CO2 come from car tailpipes just from driving back and forth to the grocery store. --- https://csanr.wsu.edu/how-do-grocery-and-meal-kit-deliveries... > While it is common for the consumer to associate convenience in the food industry with increased greenhouse gas emissions, this is not always the case. Results from a 2013 University of Washington study indicate that grocery delivery has the potential to reduce carbon emissions anywhere from 20 to 75 percent (Ma 2013), while another study out of Finland found the potential for grocery delivery to reduce emissions by up to 87 percent (Siikavirta et al. 2002). --- https://www.nytimes.com/wirecutter/blog/shop-online-sustaina... > Buying goods online can be better for the environment than in-store shopping for one fundamental reason: With online shopping, a single truck or van can replace multiple car trips, by multiple households, to stores. It helps to think of it this way: In most of the United States, almost every purchase means putting a vehicle on the road—either your own or a delivery company’s. --- Some others: https://blog.sevensenders.com/en/ecommerce-carbon-footprint-... https://web.archive.org/web/20250302115526/https://sustainab...

| ▲ | shagie 3 hours ago | parent [-] | | If the goal is reducing carbon emissions, making shipping emit half as much (650 Megatonne to 325 Mt) would be less of a gain than making trucking emit only 80% of its carbon (2,230 Mt to 1,830 Mt). The question is which is easier to do (ROI)... to cut the shipping fuel carbon footprint by half, or over the road trucking (that's about 1/4th of all the shipping) by 20%? For that matter, moving 25% of the over the road trucking to rail would accomplish that too. | | |

| Last time I checked (a few years ago), it was cheaper to send letters and small packages from South Korea to Germany than from Germany to Germany. The delay was also not that big (maybe 1-2 weeks instead of 3-5 days). I already envisioned an arbitrage business for this: a simple page where people upload their non-urgent letters as PDFs, and I just print and mail them from Korea. |

| Somewhat off-topic, but when I click on "Case-Mate - Case for 2009 LG Xenon - Marsala"[1], the "About this item" section simply states: About this item - Do - Not - Buy - This - Product What on earth is going on here? [1]: https://www.amazon.com/dp/B09D51KNQM |

| ▲ | nunez 42 minutes ago | parent | next [-] | | It might be a placeholder product to hold the ASIN. Some (many?) vendors on Amazon will recycle pages this way. Sell some item, change the item and description to dummy values when it stops selling, change to another item that will be sold, repeat. This is usually done to keep the reviews, though I've also heard about this being used for money laundering. | |

| In Poland, OLX (basically equivalent eBay) commonly has promotional campaigns, where you can buy something from a select category with 1 PLN shipping to box machine (around $0.30). So people figured out, that you can abuse it to send anything to anyone in the country. Just create a fake listing for 1 PLN, let the receiver "buy" it (there is some extra service fee, but like $1) and there you go - probably the cheapest shipping possible, much cheaper than regular ~$5-7 box machine package. |

| I've used something like this list to get "over the hump" for $35 to reach free shipping without prime. It's horribly annoying to have a product that is $34.99 and you want it, but it'll cost shipping unless you get the damn Volkswagen screw; and then Amazon ships them individually anyway. |
| |
| ▲ | mystifyingpoi 7 hours ago | parent | next [-] | | Just play their stupid game. My wife does this all the time, buys random items just to go past the free shipping range, then the item goes into trash (or is returned, if possible). Even sellers started doing this, but instead of selling random items, they sell "extra hardened packaging material" conveniently at $1, $2, $3... prices. Of course when item arrives, no extra material to be seen. When questioned, one of them said "well, the package had cardboard box - that's it, wink wink, please do not report us". | |

| Don't give money to amazon that is better spent on an amazingly efficient postal service. Amazon is subsidized by imaginary money until they put all their competition out of business(including USPS). |
| |
| ▲ | Fwirt 9 hours ago | parent | next [-] | | My honest question is: If you pull shenanigans like this, isn't it actually making Amazon burn through said imaginary money, thus hastening its demise? The cost of delivering a potato has to be on the order of at least a couple dollars. | | |
| ▲ | roncesvalles 7 hours ago | parent | next [-] | | I don't think Amazon is losing money. It's really just that efficient. E.g. an Amazon van rolls through my street multiple times a day. What is the marginal cost of them stopping at my house and dropping off a potato? | | |
| ▲ | PaulDavisThe1st 6 hours ago | parent [-] | | At your house it might be fractions of a cent. At my house, it's a 140 mile round trip between the fulfillment center ("are you feeling fulfilled yet?") and the drop off location. OTOH, there's likely more of "you" than there are of "me" ... | | |
| ▲ | ajdlinux 4 hours ago | parent | next [-] | | Assuming it's the US we're talking about, the federal minimum wage is $7.25, which means that if every worker involved is paid at the minimum wage, you incur a cent of labour costs every 4.97 person-seconds. AFAICT, most Amazon workers are paid substantially higher than the federal minimum wage. And that's just labour costs. While Amazon is efficient, "fractions of a cent" is probably the wrong order of magnitude for even the most efficient order. | | |

| |
| ▲ | saaaaaam 3 hours ago | parent | prev [-] | | You might be 140 miles round trip to the nearest fulfilment centre, but you're almost certainly closer to your nearest neighbours who regularly buy stuff from Amazon, so the van is probably coming pretty close to you any way. |

I can almost guarantee that everyone mentioned in that blog post is a habitual Amazon user. They're all renewing Prime each year at full price and making a ton of regular purchases. The family has even turned on the FOMO by making Prime a family social network with social pressure to stay. I see it as a self-own, personally.

| ▲ | bandrami 2 hours ago | parent [-] | | If you put all of the money Amazon as a whole has taken since it was founded in 1994 in a stack on the left, and all of the money Amazon as a whole has spent since then in a stack on the right, the stack on the left is slightly larger, but this has only been true for a couple of years now. It's the difference in 1990s billionaires and 2020s billionaires. Bill Gates was so rich because he owned a lot of Microsoft shares and received profits from those shares as dividends. Jeff Bezos is so rich because he owns a lot of Amazon shares and people keep being willing to pay more and more for those shares so his notional net worth increases (AMZN has never paid a dividend). | | |

| ▲ | umanwizard 6 hours ago | parent [-] | | Which is a totally valid reason to hate USPS. The USPS is a government-run spam delivery service that there is no way to opt out of. Those of us who do banking and other administrative tasks online would be better off if the government shut it down completely, or better yet subsidized it slightly so it doesn't have to deliver spam to survive. But as it is, I don't see any good reason to have any more respect for USPS than I do for any other spammer. | | |
| ▲ | lkbm 3 hours ago | parent | next [-] | | Doesn't seem like USPS is the spammer. They're Gmail. People send spam and USPS/Gmail delivers it. | | |
| ▲ | umanwizard 2 hours ago | parent [-] | | No, it’s completely different. Gmail actively tries to prevent spam. If they catch you sending it, you will be banned, and they let individual users block whoever they want. A huge part of their product is automated spam filtering. On the other hand, spam delivery is the business model of USPS. They actively and intentionally market and sell their services to spammers, and not surprisingly, give normal users no way to opt out. |

| Funny seeing this. I've been working on a site to allow people to send a letter as cheaply and conveniently as possible. I actually think letters (physical) are a great way to make an impression, often times much more so than an email. Had never considered sending an actual object lol. At current scale (which is very small), the cheapest I can get it down to without losing money is $1.55 per letter (postage, paper, print, envelope, stripe fees, misc. hosting fees, etc.). Sadly, I have no way to compete with a $0.25 lime! If you're curious, https://mappymail.com |

| Turns out, at least in my area, for the grocery items you need to buy at least $25 worth to qualify for the free shipping. |
| |
| ▲ | modeless 9 hours ago | parent | next [-] | | Yeah, this is misleading. You can't send a lime for $0.25. It's $3.24 minimum. | |
| ▲ | sciurus 7 hours ago | parent | prev | next [-] | | I checked the first five items while logged in with Amazon Prime. They all required a minimum order of either $25 or $100 to get free shipping. | |
| ▲ | andy99 8 hours ago | parent | prev | next [-] | | I canceled prime ~8 years ago because where I am, half the stuff I wanted was considered an “add on item” that could only be shipped free if you had > $35 of other stuff, which is a complete scam because you get that without prime. Maybe that was just for me (in a large Canadian city at the time) or maybe they don’t do that anymore? I haven’t considered getting prime since, it would be a lot more interesting if it actually provided the shipping terms they advertise. | | |
| ▲ | ics an hour ago | parent [-] | | It was like that in NYC at the time as well. I'm not sure when it stopped but have not seen add-on items in a long time and most things seem to ship immediately regardless of price (with Prime). | | |
| ▲ | crazygringo 30 minutes ago | parent [-] | | Yeah, haven't seen in a long time either. I can't help but wonder if it's related to Amazon building its own delivery infrastructure instead of relying on UPS/USPS like it once did? (At least where I am.) |

| The DoorDash pizza arbitrage comparison is apt. Both cases expose the same fundamental thing: venture-subsidised pricing creates artificial market conditions that clever people will exploit. What I find interesting is how long these windows stay open. You'd think someone at Stamps.com or UPS would notice the pricing anomaly, but large organisations are often too siloed. The team setting international rates probably doesn't talk to whoever monitors small parcel economics. The author mentions making a few hundred dollars - but the real question is scalability. At what volume does this become attractive enough for the postal services to close the loophole? There's probably a sweet spot between "not worth their attention" and "actually profitable." |

| This needs to be updated to check if an item is just local delivery. Most of the items are not available for delivery unless you live close to a fresh. |

| To the author, would you consider changing the “key photo”? I sent the weblink to a friend, and the key photo in iMessage is the pregnancy test and they got the wrong impression about the site/prank. Pick the lemon or can of beans perhaps? |

| There are also things on eBay with a starting price of less than a dollar with free shipping that never get bids. I "won" two auctions like this the other week for brand new USB-C cables, each of them costing me 13 cents shipped. I have no idea why sellers would do this with eBay fees and USPS small package shipping costing well over 13 cents. |

| ▲ | crazygringo 24 minutes ago | parent [-] | | Presumably they are inexperienced sellers who haven't learned about reserve prices? Now you're part of their education. Or... they are sophisticated and trying to get a ton of relatively inexpensive positive ratings? |

| The lowest I found is two clip-on CAT5e cable termination jacks for $0.80 + 0.08 tax. Available in a rainbow of colors and shipped free to Seattle by Sunday if you order in the next 10 hours.

| I get the point, but this seems pretty out of date. Seems like it needs a [2025] (?) at least. A couple of these are still valid with Prime, but most of them are Amazon Fresh items ($9.95 service fee for orders under $50), or out of stock, or the price is now way more. |

| Tempted to start paying cash to mates to drive us to and from the airport. We have to pay for the ride either way - may as well put it in a friend’s pocket. Tempted to vibecode a little tool to manage ride requests.. |

| But the cost of Amazon Prime have to be factored in as well |
| |
| ▲ | bigstrat2003 9 hours ago | parent | next [-] | | Only if you weren't already paying for Prime. If you were, then it's irrelevant as this usage adds no marginal cost. | | |

| ▲ | OkayPhysicist 8 hours ago | parent [-] | | well, yeah. That's what the phrase "marginal cost" means: if it costs $x to do something N times, and $x + $y to do something N+1 times, $y is the marginal cost. |

| I'm super surprised there is still free shipping for small things. In (some) other parts of the world, they will charge significant delivery fürs for anything below $50 or so. It basically changed during Covid, and since every shop is now doing it, there's no competition on that. |

| There’s an even better way to send an actual letter for free. Simply switch the destination address on the envelope with the sender address, and drop it in the mailbox. When then post office returns the letter to sender because of insufficient postage it will have delivered the letter for you. |
| |
| ▲ | lkbm 2 hours ago | parent [-] | | Keep in mind that in the US this is illegal, and it's unreliable, since insufficient postage mail isn't necessarily returned. This is one of the oldest forms of mail fraud, and they're well aware of it. |

| A cheaper option (if we’re going to do away with the restriction that the post card should be sent by the sender) would be for the recipient to hook their printer up to the network, and just send bits. It is better, actually, you can even scan a real hand written post card. |
| |
| ▲ | wizzwizz4 9 hours ago | parent | next [-] | | We could even make a standardised protocol, where anyone could send messages to any connected printer: like letters, except a facsimile of the original document is produced. I'm struggling to think of a catchy name for this, though. | | |

| ▲ | rationalist 6 hours ago | parent | next [-] | | I'm sorry the ink cartel hurt you. May I introduce you to the world of laser printers? My color laser printer has definitely been cheaper than me driving to the store hundreds of times to print thousands of color prints. | |
| ▲ | itintheory 7 hours ago | parent | prev [-] | | I think it depends. I bought a Dell 1700 laser printer for the low price of $0 at a second hand store about 19 years ago. They said it was failing to pull paper from the tray, and I could have it if I wanted. I fixed the rollers responsible for feeding (turned the rubber wheels inside out), and used it for another 10 years without issue. Sure, toner costs some money, but an off-brand toner cartridge is $25, rated for 3000 pages. I have also needed to replace the drum, and at one point picked up a second 1700 into which I had to put the old drum and toner after some failure or another. I'd estimate I've put in $200 at most, and probably put 15-20k pages through it. Still prints just fine. It doesn't have color, or networking features, but I can share it on the network from the connected computer. I'm not sure they make anything this reliable these days, but I bet there's quite a few old laser printers floating around still. |

| Has this person tried it? Doesn't Amazon shipping have to go to the billing address on the credit card? Being able to purchase on a credit card and have it sent anywhere makes it that much easier to use stolen credit cards. |

| ▲ | AnssiH 6 hours ago | parent | next [-] | | > Doesn't Amazon shipping have to go to the billing address on the credit card? No, I've had stuff shipped to plenty of addresses. | | |
| ▲ | kazinator 5 hours ago | parent [-] | | It looks like the billing address restriction was a "thing" years ago, but is simply too impractical for modern day e-commerce. People want to do gifting, or get things delivered to temporary accomodations like vacation spots. They are relying on approaches like heuristics (sudden purchase for something expensive going to an unusual address), plus CVV verification to help ensure that the purchaser physically has the card (still allows theft, but adds a layer). |
| |
| ▲ | toast0 7 hours ago | parent | prev | next [-] | | You have to provide the billing address for the card. But you don't have to ship there. Plenty of people ship to the office. I buy stuff for my parents from time to time. When I'm on vacation, I might ship to the hotel or a friend I'm visiting or ... | |
| ▲ | SoftTalker 7 hours ago | parent | prev | next [-] | | Pretty sure if you buy something as a "gift" (which is what allows the inclusion of a message) then you can send it to a different address. I rarely use Amazon and never have used it to send a gift so could be wrong. | | |
| ▲ | umanwizard 6 hours ago | parent [-] | | You can send things to other addresses regardless of whether it's a gift or not. | | |

I'm not aware of any e-commerce site that has a restriction like that. > Being able to purchase on a credit card and have it sent anywhere makes it that much easier to use stolen credit cards. Well, it's probably one fraud signal among many, but it's absolutely not generally prohibited. I've sent things from Amazon to other people (or to myself while staying in a hotel), and other people have sent things to me, many times. |

| Debunked in the first click: $0.25 - Lime - Amazon Fresh -FREE 2-hour delivery on orders over *$100* Other products have similar shipping restrictions, or the prices are higher than claimed. Also, most of the cheapest products (at least before tariff effects kicked in) don't allow customized messages that postcards allow, for obvious reasons. |

| Isn't postal arbitrage how the original Ponzi scheme started? |
| |
| ▲ | wat10000 7 hours ago | parent [-] | | Indeed. Ponzi attempted to buy International Reply Coupons in countries where they were cheap, then exchange them for stamps in the US and sell the stamps for much more than the purchase price of the IRC. Of course, it didn't work. There wasn't anything fundamentally wrong with the arbitrage scheme, but the profit per coupon was way too low to make it feasible as a business. Ponzi pivoted to paying off older investments with new investments, and the rest is history. |

| > You're not only saving money. That's right, you're also cementing Amazon's control of the US economy. Both by doing more business there, and by spending time on that site which will lead to you doing even more of your business there. Not to mention having to be an "Amazon Prime" person to begin with. This may sound weird to some, but - you should really avoid using Amazon where possible. |

| A more recent question I have is how Amazon is skipping DeMinimis fees which are now massive on 50 cent or $1 items from their "Amazon Haul" which come from overseas It arrives in a few weeks by Amazon's own carriers, not USPS/UPS/FedEx Who is paying the $80 DeMinimis fee on the $1 cable I got last week from China? |

| I can almost guarantee that everyone mentioned in that blog post is a habitual Amazon user. They're all renewing Prime each year at full price and making a ton of regular purchases. The family has even turned on the FOMO by making Prime a family social network with social pressure to stay. I see it as a self-own, personally. |
