Gamestop has a PowerUp Rewards Pro membership which they pay you to sign up for. This is a great deal Gamestop offers that we are confused why they don't advertise it more. The membership costs $14.99 / year, but Gamestop gives you 12 x $5 Coupons. If you want to pickup simple game accessories or toys or even t-shirts every month for $5 off, this is a great deal. Some toys and used games are $5. There is no minimum purchase to use the coupons.
