Amazon does sell off some of their returned items, at least here in the states. The sell them by the truckload to auction houses, who auction off all the goods as is, with no warranty. There are multiple warehouses across several states that bring in these items, take pictures, and post them up for sale. Local pickup only, and they have viewing hours for the items up for sale. I have gotten many good deals on items that were brand new at a fraction of the cost. Not just Amazon, but also some other big stores like Home Depot and Sams Club.
