NO FPO AP address (for military)

Heard about this app on yahoo.com and immediately searched for it. I saw the price and still didnt care because its an awesome idea! I go to enter my billing and shipping address and........ There isnt an option for FPO AP (military). Why the exclusion!? None of my credit cards have an stateside address since I live in a military base overseas. Can this be fixed? I dont want to think, Ive wasted the money on an app that I wont use until I move back to the states.
