I stopped by the Sears in Bowie, MD today. They had two copies of the GBA NES classics version of Super Mario Brothers. This is the one that for some crackhead reason is going for 50$ is on ebay right now. When I got it rung up they were $3 each! Apparently they had been marked down for a long time, and were just sitting there....
Probably a very YMMV type deal since most places would be sold out by now, but just a heads up to check the local Sears if you have one.
