Simple answer - Ring and Ask for the model that you want, and if you want to buy it then ask them to reserve it for you.Will it be in stock at to store? I'm not asking you to speculate if they'll be sold out- I'm just asking if stores will have them in stock today or if they start shipping today to the stores and wont have any in stock?
I agree. Phone the Apple store in your region. If the buyer is serious about buying the product, ask the store Rep to "hold it" for you. Many stores in my area will "hold a box" for max 2 hours. Especially when it takes me 1 hour to drive to that location as well. If not sold to me within 2 hours, its "unreserved" and sold to a different person after that time. Works for me as well...Simple answer - Ring and Ask for the model that you want, and if you want to buy it then ask them to reserve it for you.
