Cashing in those coupons is where this bargain starts to get complicated, however. One of them can only be exchanged during the month of December, whereas the other is only valid during January. Also, the game is only free if its value is $29.99 or less. Any more than that, and the coupons will just subtract $29.99 from its list price. This sounds way more elaborate than it needs to be, but knowing the ridiculous lengths that gamers often go to for free stuff, we're sure that some of you will still take advantage of the sale.
