If it ships today or tomorrow, you may just get it on saturday, but I would think it would be more like monday or tuesday next week. Just a Guess.
Jan08, if you look on the apple order status page down the left hand side, you should see 3 different numbers. The top 2 are your order reference numbers beginning with W, then next one is your shipping reference number what should begin with 80, and the one next one is your consignment number. If it was shipped last monday, you should have recived a consignment number last tuesday. Your consignment number should begin with a 2 if im correct. Right at the bottom of the left hand side it will say what carrier its coming with, and this will either be TNT or UPS (generally only UPS if you have ordered something else from the apple store that doesnt ship from china).
