We can ship an order to a U.S. PO box via USPS Priority service only if it is also your credit card billing address and it is located within the United States. Otherwise we will need a physical address for delivery.
If the free shipping option is selected (Fedex Express Saver or Fedex Ground) the package will be shipped via USPS Priority. If shipping is upgraded to Fedex Overnight, we will ship via USPS Overnight.
We also ship to APO addresses via U.S.P.S. Priority only.
