When retailers begin taking those kinds of discounts off of product, on such a large scale, it's usually due to the manufacture offering what's called "Vendor Credit". Best Buy negotiates that sort of thing pretty aggressively, so as not to just eat the costs, especially when our stores stop placing orders for replacement stock if the manufacturer won't accommodate those sort of deals. You think WalMart, Best Buy, Amazon, etc. all would just start taking that hit with no recompense? I swear, people have no idea how retailers work.
