Amazon appears to be determined to make itself an untrustworthy place to buy stuff. It's like it's actively trying to get itself lumped in with eBay as a "tat-bazaa" as The Register likes to call it.

I've become increasingly wary of buying things on Amazon for this very reason. I recently bought several pieces of electrical/elecronic gear, and didn't buy either from Amazon. I don't trust that the named brand stuff will be genuine, and I don't trust that the unknown-brand stuff will be any good, irrespective of the reviews. I've had too many cards with my orders promising freebies for positive reviews to trust anything I read there now.

I now pretty much only buy low-risk stuff on amazon.
