It's basically made Prime feel useless for its original purpose of free shipping on warehouse items, because if I'm buying most things that would come out of their warehouse I'd rather pay for shipping direct from a specific vendor because I don't trust anything shipped from Amazon. Maybe it's still worthwhile for other services (music, video, groceries, whatever). Sure I can get my money back if I get a detectable counterfeit, but what about my time dealing with it and without having what I ordered? And what about items that aren't easily detected as fake but which are notably substandard when used (e.g. odd-size or lithium batteries that die in 6 months rather than 2 years)? It's not like ordering from Amazon is really notably cheaper than other options these days anyway.
