I used to do this more often, but I find the gap is narrowing a lot. Most of the time I find I don't save enough to justify getting it in two weeks over 1 day.

The Aliexpress of 10 years ago was just ridiculous. One time I ordered something (a USB adapter) for literally a total price of 40¢, and it was delivered. It cost about 35¢ to send a regular US postcard domestically at the time, not counting the price of the postcard.

Now all the 40 cent items cost $2, and have $3 shipping. Or you can buy the same thing on Amazon for $6. Their search also used to be a lot better, today it's worse than Youtube search.

We have a very large Amazon warehouse/center in town, and during my last prime trial I received maybe 5/25 items listed under “2 day shipping” in actually 2 days. Nearly all took 4 or more.

Cannot even imagine 1 day.
