If your using a different shipping address to a billing address when buying from the Apple store UK, make sure you have a fax machine and bank statements / driver's liscence at hand. I ordered mine and had to fax all this stuff off within a few days, and since i missed the deadline, my order was cancelled and i have had to order another. I suppose it is obvious and i should have thought of it, but if anyone else is doing the same, make sure you are prepared!
