I was at Sam's Club the other day and was somewhat surprised to see a whole bunch of black 4GB Nanos. they had the 2'x1' plastic sheet, which you would take to the register to redeem for the merchendise. I was just wondering if anyone else had seen them before and how long they have been there. They were undercutting traditional Apple pricing by $5 or 10, I can't remember exactly, not a lot, but something none the less. As a corallary, based on the appearance of the Nanos, would it be reasonable to expect traditional iPods as well? And more importantly, how does the Sam's Club return policy work with Apple rules?
