> I use Amazon only for books these days since I figure it'll be difficult to substitute a scam item for those
Unfortunately you're wrong, it's a huge problem for books as well. No Starch Press already left Amazon because it was the only way to prevent fakes being sent out to customers buying the genuine book. Fakes including ones where the back cover wasn't printed or everything was printed black & white, low-quality paper etc.
As Amazon just mixes fake & genuine products because they say the same thing on the package it's impossible for both sellers and buyers to know what they'll get. You get what the person handling the package will draw next from the pile.
