It’s a business.
And sometimes Amazon.com is an outright con. Same buyer, multiple problems. Never got clear answers as to why/how or immediate re-compensation.
I bought a $6,000 camera and AMAZON sent me ROCKS!!

There are variety of sizes if clothes, underwear, shoes, hats etc... and the sizing varies from country to country, manufacturer to manufacturer... it is frustrating to the customer that every year or so a particular item that fits well is discontinued.
Unless these clearing houses get a handle on product standards they should expect returns. One size, or wrong sized does not fit all.
I have a sister, who used to be a purchaser for a large department store chain, and she would go up to the Garment District quite often and pick up bulk supplies of perhaps blue jeans, send them somewhere to be labeled with the store brand patch & sold. She told me that she was pretty good at ensuring all sized jeans or product was accurately marked & not incorrectly sized. I don’t think that’s happening any longer, so perhaps the problem is in the purchasing agent qualifications and so on the shoulders of the company itself.
Fortunately I have found that LL Bean is very consistent in their sizing for me. However that said, I have received items from L.L.Bean that were sized incorrectly, based on other products from L.L.Bean that were correctly sized. I’m lucky, in one regard, but it is almost impossible for me to walk into a store and buy anything off the shelf as I am outside the 90th percentile in length. And that goes from Cars to clothes. Costco never sells anything in the outerwear Department that is long enough in both sleeve and inseam.
