Walmart Unwittingly Sells iPod Nano Knockoff as Actual iPod and didn't seem to give a damn when a concerned customer explained to them the differences between an Apple branded iPod Nano and the piece of shit knockoff (I can say this because I have actually tried to help a kid who had one of these things and it was utter crap, I felt bad for the kid).
Wal-Mart doesn't care what they sell just so long as they get their greedy little hands on every last dollar in your wallet or available credit on your account. They'll even sell you a fake iPod Nano and call it real (and probably charge you the full Apple price for the faker while they're at it).
