Nah, the company I worked for bought truckloads of the returns absolutely AS-IS salvage. There was no guarantee to anything that they purchased from best buy and circuit city.
We just threw the blocks of wood, and old hard drives into a huge heap, and sold that huge heap as a pallet of parts.
This company from mexico would come and buy pallets and pallets of broken electronics. I have no idea what they paid for them, but they would make runs from mexico to buffalo twice a month with trucks similar to a fedex truck. Mexican license plates and all.
