I'm surprised Amazon isn't more on top of this.... The last thing they need in today's anti-counterfeit/anti-piracy trade environment is a highly visible, easily verified product being offered for sale by Amazon itself.
Amazon has tons of 3rd party listings for stuff that is bogus. There are more than a few listings with fake SD cards on both .ca and .com.
Amazon does not care as they only guarantee what they personally sell is real. No government is going to even dream of punishing Amazon for anything like this.
