I pre-ordered GR from Bestbuy only to find out when I picked it up and opened it that there was no pre-order code for the pre-order DLC! Does this mean I'm totally messed up for the pre-order DLC?
I think most retail outlets just print the DLC download code on the receipt. Hope you didn't throw it out...
I preordered it from Best Buy as well, and they told me that it's on the receipt. That's where my code was. It's not on the preorder receipt, but the purchase receipt. Even if you throw it away, the employee told me that if you are a part of their gamer club (whatever it's called), they also send it to your email. Good luck!
