If you're looking for an easy and cheaper way of shipping, use pirateship.com Its totally free to set up an account and they have discounted rates though USP and USPS. I use them all the time and it has saved me a lot of money over the past year.
And no, I don't work for them or have anything to gain by posting this. Just trying to save everyone a few bucks.
