As a former retail employee let me explain why stores won't sell busted things at a discount. When something on the floor gets broken or damaged the store claims it as broken and gets their money back from the manufacturer, at Kmart we had a girl who's entire job was to collect the UPC's from damaged items to get refunds. The manufacturers evidently put up with this to keep their items on the stores shelves. Not discounting broken items also discourages customers from breaking items to buy them cheaply. Once the claim had been filed for the item part of the agreement with the manufactuer was that the item would be completely destroyed, once a week or so we drug all of the claimed items out into the back parking lot and smashed them with sledge hammers. I've broken down dented file cabinets, dented microwaves, gun cabinets with cracked glass, various small home appliances, furniture, all kinds of stuff. This was also intended to deincentivize dumpster diving, everything we threw away was broken beyond use.
