Thanks for the tip, OP. I picked up Riddick, Yager (XB) for $10, and two Japanese limited edition XB controllers, the last two they had.
I used the GGC coupon on one of the controllers and it not only took $5 off the controller but $5 off Riddick too. The cashier noticed it, but there was a longish line, so he just said, "well, we'll just go with it" and proceeded to ring me up. So I actually got Riddick for $10. Not bad.
