I was just about to order it but then looked at shipping. Ships: By Aug 28th Delivery: Mail (within 5 days after it has shipped) or carrier (extra 15) (within 4 days after it has shipped)
If it comes on 28th to me, then it should ship today or tomorrow (it would be late anyway)
What I know and have heard from people here, Apple ships through slowest and cheapest possibility, FedEx Ground service (I guess). It'll be faster IF you pay extra. It took over a week for my iMac to arrive from CZ to Finland and the distance isn't big, maybe 3 hours with an airplane.
