I went to my local Gamestop today to trade a couple of working complete NES systems and was shocked when the clerk told me I would be receiving $20 store credit in total. It wasn't that long ago that I traded in two others in for $35 each. I am sure this is some type of supply and demand thing but has the price dropped this low before? Does it tend to get higher during a certain time of year? If this keeps up I will need to sell them on Ebay and go through that whole hassle. Is this price chain wide or just at my local store?
