Great news for you APO/FPO customers!
I just got a message from customer support at ImageKind and they told me two important pieces of information:
1) Thay are actively working on a way to ship using USPS mail, thereby opening up the APO/FPO/PO Box customer base, and...
2) If you e-mail or call them with your purchase request they can arrange for a USPS shipment NOW.
I love this company.
