When you buy something, hopefully your first instinct isn't to just return it. Sure, things happen, and that's more than likely why Best Buy, one of the nation's largest electronics retailers, has decided to go ahead and start looking at making it possible for customers to sell their wares back to the store. First it was killing restocking fees. Now they've got something new. They're calling it the Best Buy Buy Back Program, and it's designed for those who are worried about their devices becoming obsolete after they make their expensive purchase.
