which makes me wonder why it is being sold again if it was returned as defective.
Because some people lie to get a refund? My friend's AC3 from that deal they had for $33 didn't work (disc 1 was loose and scratched up), so we had to return it. When I saw all the options, there were a lot of ways to abuse their return process. It's just part of the business of being a large retailer really. Should they inspect the returned items if listed as defective? Yes, but I'm sure a significant amount of their items are just returns that probably still function.
