This is true but you can still get Borderlands 2 for $18.74 with this deal, which is not to shabby. It's a great deal if you were going to spend full price for BioShock: Infinite. Also don't forget there are a handful of other games that you can get completely free with this deal (e.g. NBA 2k13, Borderlands 1). Also, you can get XCOM for $13.11, not free but cheap as you'll find it.
I wouldn't use the coupon on this, GMG has xcom for 16 dollars(or at least it was yesterday....) BTW Xcom, great game.
