I just assumed that it was an active promo when I went in too, but it didn't apply automatically. I had to tell the cashier about it, and he scanned something on an iPad to get it to work.
Managed to flip State of Decay and Resident Evil Revelations 2 that I got for $6 each from Redbox for $32 in credit today with the $10 bonus. Pretty solid.
After signing up for the rewards, going through the account verification process, entering the code, then verifying the AMD code you are taken to another screen where you accept the steam code, and that's where I got stuck.
So I bought the GCU and a few minutes later put $5 on Watch Dogs, but on the receipt it still came up full price. Does the GCU take some time to kick in and will I have a problem adjusting it on Tuesday?
