Go Digital with Steam. It is their Summer Sale this month.
Just be careful. The deals will drain your wallet. Go in to buy KoTOR, come out with Torchlight II, Saints Row IV, Surgeon Simulator 2013, Borderlands and The Walking Dead, all for 22 dollars.
EDIT: You better get your butt over there now, KoTOR is 66% off! $3.39!
