The point is that if BestBuy refuses to make it right for you, a manufacturer who cares about customer service and their brand may step in and give you a refund/replacement even though they're not obliged to. Which is what OP is doing instead of saying "not my problem, deal with Apple" to his customers.
Okay, maybe it happened because it was something cheap, a 30$ Brita Filter, I bought at Canadian Tire and ran into issues, I've contacted them and got the cheque with full refund. It really depends on Customer Service, I would buy another Brita product for sure.
