I took all next week off (not for the game... but it is a plus that it overlaps)... plus friday is a holiday so the mail guys won't deliver that day. The shipping on game stop says 1-2 business to process and 5-10 to ship. I double it would take that long but if that is the case it won't even make it by the weekend.
I wouldn't be out any money... I would just return the one from the mail if I get the one from the store. The biggest issue is I actually want the hardened edition... and I don't know if they would have that for no preorder anywhere.
