The key to Best Buy is keeping the receipt, or paying by credit card. If you lose your receipt but know about when you bought something (by credit card), they can look the purchase up and issue you a copy receipt. Then returns are a breeze.
Of course, this technology is a bit scary. As far as I know the first company to start tracking that way was Target, and we know how that's turned out.
