I just used the printed off coupon - didn't scan, but he entered it.
Picked up Chrono Trigger, Namco Museum Collection (360) and magically found a used copy of Soul Bubbles...
Good trip all around!
I'm really thinking about biting on the Best Buy GH 3 bundle... I've never owned a music game and the cost of entry nowadays seems prohibitive... but if I can get that plus two wireless guitars? Gold.
