Word for those who'd like to pre-order as well - Create your account _before_ ordering. Perhaps this was just a one-off issue I had, but I tried setting up an account whilst ordering, as the website suggested, and it erred, charging my card but not sending me any receipt or creating any account, AFAICT. It may be that it's just a fluke, but you may as well be cautious.
