I used to be like you. But overall the return culture changed drastically - "no fault" returns where stores have zero care to hear about how their items are defective. And then Amazon's constant games with pricing has pushed me into "buying" (ie caching) something if it's a good deal, and then making the actual purchase decision of whether I want it sometime later. Much better than "I'll think about this tonight", and then going to buy it and the price has jumped 30%, making me feel like a sucker.

If I've already got pending Amazon returns to do, adding something to the queue costs me very little. If the queue is empty, then I'm a little more deliberate. But this time of year Nov-Jan is great for this, as the return dates are further out and all on the same day Jan 31 so it doesn't catch me by surprise.

The slow spiteful shipping also pushes me into this behavior when I'm in the middle of a project. Order a few different types of a thing, decide exactly what I need when I'm in the middle of doing, and then when I'm done with the project, return the pile of leftovers.

It's felt like something enabling this dynamic has been waiting to break for years now, but so far it hasn't. The only time I've gotten pushback from Amazon is a nastygram interstitial for a while after I returned a motherboard that I opened and tested (the manufacturer could have avoided this return by documenting the IOMMU groups, but once again... return culture). I have no idea if the problem there was the opening (seemed to be fine under their published policies), or whether something else happened to the item after I handed it to their return agent and they blamed me.
