I recently dealt with a merchant in Aliexpress who was intentionally selling things well below market price, not to build their storefront reputation, but to collect sales and then ask the customer to cancel. I forced them to cancel the order, which harms their rep.
Literally every unmanaged, user content controlled platform devolves into the basest scams, thuggery, and unpleasantness. This is why we can’t have nice things.
Recently I attempted to return an item to AliExpress. They gave me a USPS return label with a domestic address that Google Maps showed as some generic office building. This address turned out to be an undeliverable and the package bounced back to me. Support couldn't explain it and said I'd have to pay for a replacement label since I guess they only pay for one return per order. I filed a chargeback instead. It was approved immediately. Surprisingly, AliExpress didn't ban my account or card, and I still shop there instead of equally terrible Amazon or eBay.

How does that help them?
It’s as if all the people working at physical stores, who we decided were pointless waste of money, actually had some function.
