And yet look at all the non-book products being sold on Amazon that are all garbage. Its the same slop problem and has been for a while, but they don't seem to be addressing that either. I have to assume it doesn't impact their bottom line as much as we think it should, consumers don't (or can't) care as much as we would hope.

Does it really impact people that much though?

There are two categories of (physical) products I buy on Amazon.

Regular “brand name” items sold in pretty much any big box retail store. I have more or less the same experience with Amazon as I do Walmart or Target or wherever for that category. Over thousands of orders I’ve never received a fake or had an issue outside of very rare packaging issues like damaged boxes.

The other category is “trash I need faster than aliexpress” and it’s basically exactly as-advertised for that junk. I usually get the item in two days or less where I am, and the quality level is more or less the same as ordering direct from China. Just trading expense for quicker latency. Useful for that last component for a project or whatnot.

I get that I might not be normal though. If I went to Amazon and searched for “grow lights” and got presented with what you get via that search I’d be quite frustrated. But I tend to research exactly what I want for those product categories and never had a problem getting what I expected.
