Most of my pre-orders from Amazon never ship until the day before. It was unusual to get the notice this early, and to get the promo codes so early as well. I wouldn't worry if I were you. It's most likely already shipped but they haven't updated your account yet. Typically I get the shipping notice the night prior despite it being shipped much earlier in the day.
Ok thank you very much. I am just a little worried as they changed it and now will not ship te game to australia. So yeah thank you!
