Someone mentioned Best Buy in the Cambridge Galleria Mall not having many cheap games. I can tell you now that the reason for that is because if a game is marked down dirt cheap, the employees will scoop 'em up and sell them on ebay.
I also remembered another place to look for some games~ Newbury Comics (Back Bay, down the street from the Prudental). I haven't been there since Oct. but they had quite a few new and used games with widely varying prices. I remember used copies of Metroid Prime, Dragon Ball Z Budokai, Shinobi, and Way of the Samurai were $11.
Thanks for the info. How did you know that about the Cambridgeside BB employees? I'll have to check Newbury Comics next time I have a meeting at the Pru. Does anyone know anything about the BB at Landmark Center?
