GameStop offers four used games priced $4.99 or less for $10. (Add four games to cart to see this discount.) That's a savings of up to $10 on four games. Plus, orders of $24.99 or more receive free shipping via coupon code "SAVER"; otherwise, it costs $5.99. While you can save on hundreds of games for PlayStation 3, Xbox 360, Nintendo Wii, and Nintendo DS, you can also bag games for consoles as new as the PlayStation 4 or as old as the NES.
