Best Buy: Buy 2 used games, get a 3rd for free + free shipping

At Best Buy, buy two used games and get a third used game (of equal or lesser value) for free. (The discount will apply automatically in-cart when you add three eligible games.) With free shipping, that's tied with our mention from three weeks ago as one of the best discounts we've seen for used games from Best Buy in recent months. (We saw buy two get two free in January.) Sales tax is added where applicable. Best Buy carries used PlayStation 3, Xbox 360, and Nintendo Wii games, among others.
