I doubt anyone has ever really wondered what happens to the stuff you either trade in or sell at Game Stop for about 1/3 of the price you originally paid for. (or +30% if you are a rewards member, excluding hardware)

BUT in case your that one person that did wonder, well wonder no more.  Kotaku has posted such information, so now, maybe YOU can sleep a little more soundly at night.
