You'd be surprised how many factory electronic components on Amazon are being advertised by "legitimate" vendors who are selling Chinese knockoffs. I just had a first-hand experience with this by purchasing a factory Nikon battery from what appears to be a legitimate Nikon dealer and receiving something that barely holds charge. It's not all so black and white.

No, Amazon is forcing buyers looking to purchase goods to accept counterfeit crap at retail prices.

If I want a fake DVD, I can pay $3 in Chinatown, I don’t need to pay Amazon $20.

If you stay within the "amazon.com" domain, it is often the case that this stuff is all you can find there, at any price for the class of thing you're looking for.
