While you can use a Flat Rate shipping option to work with USPS Flat Rate boxes, there is more you can do to integrate E-junkie with the U.S. Postal Service.
E-junkie is pre-integrated with the U.S. Postal Service. Here is how it works, we take the weight of the purchase, the number of packages, your zip code and the buyer's country and zip/postal code and send that to the USPS servers. Their servers take the information and then send the shipping rate back. This is all done at the time of the order and is so quick your buyer will not even notice it.

You can choose a country if you want or just let the USPS servers calculate the rates for all of your shipping.
