I seem to return 1 out of 8 Amazon items, even eating the occasional cost of poor quality items, because I needed -something-. They seem more and more to make me print and mail stuff back, first making ups pickup no longer the default, and now removing the option altogether.

I get lots of seemingly purposely mislabled products in the automotive section now. I think i get maybe 50% success rate ordering car parts. Lots of fakes. NGK, DENSO, and HONDA products seem to be prolific with counterfits. Had good luck with GM and Toyota parts so far, but I expect that to change, or be a fluke. Their automotive idea may see profit, bit I think they underestimated the extra complexity and returns inherent. Brick and mortar stores do much better at soaking up cost of returned parts I suspect.
