If you beat games and never touch them again Gamestop has a promotion for you. The retailer promises to buy back all copies of New Super Mario Bros. Wii for $30 if you purchase it from them, online, and trade it in by December 20, 2009. They're offering a similar promotion for Left 4 Dead 2 where you get $40 back if you trade it in by the same date.



In both cases, you're spending $20 plus tax to "borrow" a game for a little over a month.
