This only applies to MBPs and only as long as they are shipping direct from China.
It looks like the MBs ship from the states but the MBPs are coming direct from China right now. As such there is no difference in the "free ground shipping" and any of the expedited methods since it's impossible to drive from China to the U.S.
If you pay for 2day or next day you are throwing your money away as the only way Apple computers ship from China is "International Priority Direct Distribution." Under this shipping service FedEx has 4 days to get you your computer. Picking 2day or next day will not get you your computer any faster, it will just make you a few bucks poorer.
