Hi, I've pretty much made the decision to buy a new iMac. I would like to buy from a physical Apple store (Meadowhall) because I can just drive there and not have to wait a few days for delivery... Couple of questions, though. - Can I get an education discount in a physical store? If so, what ID do I need? - Which 27" models are stocked in store? Will they have i5 and i7 or are these build-to-order models only? Any help much appreciated. Steve.
