While any GameStop offers used software in good condition at a fraction of the price of shrinkwrapped originals, where's the fun there? It's infinitely more convenient signing up for leading rental service GameFly, whose 6,000-strong library of titles (dating back to GameCube) trumps any traditional retailer's selection, and ships right to your door. New releases arrive in timely fashion, discs can be kept as long as you like with no late fees, and up to four titles can be simultaneously checked out. Alas, like Netflix, a subscription plan is necessary, and games can take a ways to arrive via mail. But at $15.95 to $36.95/month, it still provides considerable savings, given that a single title alone can cost nearly twice as much.
