I know how to access the C-Store its just not there and I never got email from HMV, tbh I'm never ordering from them again, it took 4 days for game to come, i never got lifetime sub discount and I dont have this email.
two weeks after release and people are still too lazy to go over their HUD and really learn the ins and outs of all the tools at their disposal.
What if he did and just missed the button altogether? Even if not what's the point of trolling?
At any rate to answer your question it should pop up in the down arrow of the HUD for me it is in visit the special unlocks section of the C-Store.
