What is the minimum OOP to buy 2 gift cards? $20? If so, this effectively makes them 50% off after Walgreens $10 gift card. I think, however, a Taco Bell variable load card starts at $15.
I know for Netflix cards from past deals that $15 is the minimum.
Taco Bell, too
So this is probably a spend $30 OOP and get $10 back, so like a third off. Still not too bad of a deal as long as the gift cards are for somewhere or something you would normally spend on.
