10% off Target gift cards. Up to $500 spend ($50 savings). Target store gift cards only (no Visa/MC or other retail cards).
I apologize if this isn't completely credit card related (mods can move if need be). I don't think you need to pay with your Target Red card for this deal. But you do need to be a Target Circle Member.
The last time they ran this promotion (last quarter I believe), I maxed out the $500 spend and I checked out with PayPal and Disco for an extra 5% CB. This quarter I will check out with PayPal and Freedom for an extra 5%.
