USPS is required for shipping to P.O. Boxes and APO/FPO delivery addresses. Na Hoku provides Free Shipping (via USPS) on orders of $200.00 or more to APO and FPO addresses as our way of saying Mahalo Nui Loa (Thank you very much) to members of our U.S. Military. While USPS states that Priority Express Mail service will arrive two days after shipping, delivery will vary to APO/FPO addresses, depending on the location and during the holiday Season.
