Dishonored is $10 for today's deal
Good luck getting this to go through!
I had this exact same problem during the fourth of July sale trying to preorder Saints Row 4. I even tried Paypal. Same thing happened. I ended up just giving up.
I tried a couple more times and called twice. I was told they have one of the most strict billing policies on the internet which is why it takes so long to process and why a lot of people get rejected. One time they said my billing email address didn't match...never even heard of matching an email address. I just so happen to put all my gaming stuff in one email and use another for just about everything else.
Even after changing the email address and copying & pasting my billing address straight from what my CC company had, I still couldn't get it to go. This is especially exhausting since you have to wait 2-3 hours between trying to order. The last person I talked to said I should wait three business days because now I'm flagged for trying to many times.
I don't see why Gamestop is even trying to get into digital distribution if they are going to make it so difficult to buy from them. I should have grabbed Skyrim from Steam directly during the summer sale. I'll just wait until another site has it cheap =/
