For me it was a Noctua fan that had a thick layer of dust built up. Who the fuck returns a $20 fan with thousands of hours of use? And why did Amazon think it was appropriate to send that trash to me when I paid for new??

Doesn't even take that much for some people to be restricted. I had someone steal one box with maybe $50 worth of stuff off of my porch and Amazon replaced it after a ten minute conversation with customer service, but a year or two later someone stole $10 or so worth of an order of clothes laundry/softener toss travel sheets from me (or they just never shipped and I paid for them) after a particularly larger number of orders (I lived somewhere else by then), and Amazon not only did not offer a refund or replacement, they removed any way to request it. I am not sure what their cutoff is or if it has to do with what warehouse it ships from. Maybe people just lie about laundry supplies a lot? Perhaps the cutoff is more to do with the type of products? I had never ordered that sort of stuff before.

It is rather gross to me that they let people return clothes and shoes that have been tried on. My current pair of like $110 trail running shoes that I bought on Amazon had been tried on when I got them, and I was a bit unhappy with that, but I decided to see that as more like a shoe store sorta thing. Clothes, not so much. I decided after trying the clothes returns policy once (never tried it on) years and years ago that if I do not want to get things preworn, I feel I should practice what I preach. It is a weird policy, at any rate.

Enshittification: Customers get screwed because that's where vendors are (even the terrible ones) and vendors get screwed because that's where the customers are (even the terrible ones.)

Happened to me. I ended up holding the bag for about 400 EUR worth of items. Luckily I had legal insurance that tried to convince Amazon to take it back but they wouldn’t, so the assurance bought the box of stuff off me and refunded me.

Fuck bezos and Amazon. Since then, I always look for alternatives to Amazon to buy my stuff. I’ll use Amazon to see if I like it, return it, and go buy somewhere else. If I know the product I’ll just straight out buy it somewhere else. It’s often the same price or very close.

Some stuff you can’t really and practically get outside of Amazon. I don’t have a choice then. Because their quality is so low, I’ll just get 3–4 similar items and only keep the one that’s passably usable.

I try to cost Amazon as much money as I can. I hate to give them my money but by doing this it feels like I’m getting some payback for the way they treat their customers, employees, delivery people…

Maybe this is a country thing, or tied into one's wider social credit score in the background, or the specifics of something you returned [0], or something else? I've returned plenty of shit and have never had a real problem. I returned over a dozen 32 inch Dell monitors while trying to get 3 that didn't have dead pixels or scratches out of the box. They were stacked on a pallet in my garage waiting for the pickup. You would think this would throw some flags and end up as some kind of fight. But no, Amazon refunded them all in full, no hassle (apart from the hassle of having to do that scale of logistics merely to obtain working products).

(I would have honestly given up earlier, sent them all back, and gone with a different brand. Except there had been a good one in the first tranche of 3 that I let go past its return date. I hadn't thought the actual failure rate was going to be > 80%)

[0] On my personal account I did have a big red scary warning for a while about "restocking fees", that I think had been prompted by returning a motherboard after having tested it (yet another poorly described product with no way to find out the IOMMU groups short of buying it). I have no idea if it was merely that I had opened/tested a computer component, or if it had gotten smashed up on the way back, or what. But eventually that nag screen did go away.
