From the customer side of things, there is one upside to people returning things - Amazon sells the returned stuff as Warehouse Deals, often at a great discount. Unless it is a gift, I don't usually (ever) care if the box is gone/damaged or if the item is slightly used, as long as it is cheap. So far, in Canada, I've never had to return a Warehouse Deals item.
