Radio Shack and Circuit City are NOTHING alike. Radio Crap is a joke of a store and sells their own brand of junk. Serious audio and videophiles avoid it like the plague. Radio Shack has been and always will be for people like the Professor on Gilligan's Island. You know, dudes who build radios out of bubble gum and scrap metal. They don't generally get laid a whole lot.
Radio Shack needs only 3,000 employees because almost nobody shops at Radio Shack. Seriously, I don't know how many times I walked past one of their stores every day after work and the place was a ghost town.
