I preordered the iPhone 6 plus and it should be arriving tomorrow. But I was not able to preorder the leather case or the silicone case. Wondering Could I go to an Apple store tomorrow at opening and buy just the accessories without having to wait in line? They might force me to the back of the line, and it would seem fair because I imagine all the people waiting in line will also be buying accessories. But what's the likelihood that they might let me buy the case without having to stand in line? I know in past years they've let a couple of people in at a time without waiting in line as long as they were not buying an iPhone but I'm not sure if that policy also includes iPhone accessories. Thanks!
