Every couple of months or so, GameStop gets bored with its usual routine of selling all of its used games and accessories, so it goes on weekend-long tears where it starts giving them away with the purchase of two other items. Fortunately for all of us, this is one of those weekends.

Through this Sunday, October 17, all of Gamestop's used games and accessories are valid in the "Buy 2, Get 1 Free" sale. This offer can be redeemed in-store or online, if you use the promo code "B2G1FREE" at checkout. No code is required to access the offer in an actual brick-and-mortar Gamestop, but we recommend giving the store clerk a hearty high-five, because hey, he or she is probably having a rough day.
