As Confoosius noted and we all know, you can't apply the gift card to the same transaction you get it from. That would be the only way to get the max savings of 41% off. Of course, if someone considers a TRU giftcard the same as cash, after one transaction you can say that you got those two games for $35 a piece...along with a $50 gift card. In any case, you've still spent $120 to get $170 worth of goods.
But this was my point all along. That the intrinsic value of the gift cards are bring considered purely for value comparison as most cags will always find a way to max out any deal or store credit. And I agree this deal isn't going to be for everyone because they are different promos after all.
