Ok, so this is a first time Apple order question, so bear with me here:
I'm buying SIM-free. I was going to order through the military site for the discount. I already know I won't be able to get the 10% any other way. I'll lose $120 if I go through the app. If I do the pre-order through the app, can I take it in to the Apple store to get the 10% adjustment later? If it's not an option, that's fine, but I wouldn't know if I don't ask.
Also, I'm not financing, I would just set up the pre-order and then pay with my credit card (better rewards) at order time of ordering. Anything missing here?
