Just picked up 1 each from Office Depot & Office Max. They are within 2-mile of my location. Manager at Depot said; "I think we got an email to pull the GameStop gift cards off shelf, let me check for you." ... 5mins later, I was granted an okay to purchase 1 card. So YMMV y'all may want to head...

A good deal on that Buy 1 get one 50% off for older value X1 games for GCU members. GCU should stack from my past experiences with similar promotions. Meaning 20% off 1st title & 70% off 2nd.
