Those are reasons a return policy is nice to have. Yes, it’s not a great idea to shop for clothes on eBay, so that can be an exception? The point is to use the giants less, it doesn’t have to be all or nothing.

Sellers get a larger margin on eBay. You can’t get perfect but you can get better. The return/exchange policy is a small tradeoff for not supporting one of the most evil corporations in existence. It’s also kind of a selfish thing to care about, most of Amazon’s returns are just trashed into the landfill so it’s not like it’s green or something.

Just use eBay

Mostly die.
