We have 2 6 plus iphones on preorder that apple says will be delivered on 9/19 so I'm going with that assumption. I leave for out of town the very next day so I want to get a case. I stupidly decided that yesterday and the midnight blue case that I would like to purchase says will not be delivered for 5-7 business days. I have never been to the Apple Store day of launch. If I am not buying a phone or picking one up, can I waltz into the store at 8am and buy a case? Is that possible? Thanks in advance.
