Earlier quoted context omitted.
For my DIY hobby I buy a ton of stuff off Amazon - usually small parts under $15 dollars. I just checked and this year I've made 602 total purchases and, after checking the return e-mails they send, I've made 287 returns this year. I just click "bought by mistake each time". If there is a social credit score based on number of returned items I still haven't hit it.
Excuse me, but do you believe this is "normal"? I mean, if you returned 287/602=48% of the items you ordered, either there is something wrong in what you order or - more likely - your supplier (Amazon) is not reliable. On the other side, if 48% of items (particularly if low value ones) are returned, the costs of shipping/returning/handling must be enormous.
This includes some parts of fashion. You buy online. If it doesn't fit, you return and buy another. There are hobbies which are similar. You buy extra parts, and return what you don't use.
The price factors in the 50+% return rate. If they didn't allow returns, no one would buy.
I don't know if that's what OP is doing, but I'm not ready to judge unless I know it's not.
