I hope this isn't breaking the rules. I want to give away an online redeemable code to someone who may be interested in it more than I am. I just picked up my copy of the Batman: AC CE and among all the codes was one for a beta for Gotham City Imposters. The back of the card reads:
Redeem this code for a chance to join the Gotham City Imposters beta and to get your free* Batman: Arkham City-themed content!
So if you're interested let me know and I will PM it to you. Thanks!
