Suitcases! Will you have friends visiting you who would be willing to check a suitcase or box (or two) of your stuff for you?
Also, you might look into UPS or FedEx ground rates
if you (or a friend) works for a big company which gets a
significant discount.
Oh, and if you know someone who works for JetBlue, I know their employees get a big discount for FedEx, but it might only be for express service and not ground...
