Call them. It's unlikely that they have them in stock but they can order one for you
Are you sure about that? I don't think Apple Stores have an in-store reservation system for ordering BTOs.
Can I shop online with a retail store and also with an educational discount?
Of course I cannot guarantee that but I can't see why not. If they can't do that, then order one online with in-store pickup, that lets you configure it. Just select your retail store from the list and click shop online, I think that's for in-store pickup, don't see what else would it be. Correct me if I'm wrong
I don't think that's for pickup. I don't know why it's not, but it seems the "Shop Online" link is just another way to get to the Apple Online Store.
AFAIK it's for in-store reservations, why would the URL be different and there reads Apple Store Arrowhead Mall above the products?
