So pretty sure Amazon sells all its returned merchandise to wholesalers who sell them really cheap.
Like “all items $2 for one hour only” kind of cheap.
I got a sweet deal on a printer that way. Like, a ridiculous deal.
But going to that place was horrible. A warehouse of poverty and desperation and people nearly coming to blows because they both want a deal on the pair of socks they grabbed at the same time.
Unpleasant, but serves a purpose.
