ronsunni is correct. You can take it directly to the shipper (I used UPS last time) and you will need a copy of the receiver's FFL license in hand. You do not have to have an FFL ship it for you, which will save you $25 or so in processing fees.
If you have specific questions, call your local UPS depot. Some may "apply" the rules differently than others!
