Military discount

Unless someone who qualifies for that 10% discount sees this and answers that may be something tthat you need to call an Apple retail location and ask.

Normal purchases online or by phone with Apple retail have a number of options for delivery; $9 2 hour delivery to some locations; free 2-day delivery or you can arrange for you or someone else to pick up most items from a retail store.

You can use the store pickup option when using a military discount. You also have the option to designate another person to pick up the order as well. You will have to designate that person like anyone else would when picking up, using their name as it appears on a valid government ID, such as a drivers license or ID card. They do not have to be a military member. I have done this in the past. I just picked up a new MacBook Air for myself, and when I set up the in-store pickup, there was a link to designate someone else to pick it up if necessary.
