If anyone is planning on purchasing one of the 12.99-17.99 games and has the 10 off $19.99 pre-owned coupon, you should try to use it on one of these games. If you get a cashier to at least try to scan it to see if it works. It might, because with the 10% gcu discount, when you buy used games that are on sale, you get the 10% off from the regular price, so perhaps the the magazine coupons will work the same way. Don't think its worth to try on the 9.99 games as it would essentially make them free.
