It's certainly degraded and I have to sift through a lot of junk but I find it's still pretty easy to identify the grift/counterfeiters/etc. I've never had a problem with returns. It's generally easy to initiate, there have been a few random high dollar purchases $500-$1000 that I didn't even notice were flagged as "no refunds" at time of purchase, but if I get on chat they have always made exception and allowed me to return it. The only annoying part is every time I do that, finding the chat feature takes me a good deal of time it's so buried in the UI

I don't buy a lot of books though so maybe that's where a lot of this is coming from?
