I'm visiting america just after the new year (Disney florida) and was planning to get a iphone, I've been checking the availblty on store pickup for a while now with nothing changing (Looking for a 6plus 64gb) So, i wanted to ask, am I correct that store pickup is for the same day only? If so, and they dont have it in stock, could I go to a apple store and ask them to order one and i pick it up a few days later?
