The form states that P.O. Boxes are not allowed. Well, I live in a mountain town that only has PO Boxes. We can get deliveries from UPS and FedEx to our house but the form for the free mophie powerBOOST mini rejects our street address as invalid (even though it was built in 1879). So how do I take advantage of the promotion when my street address is "invalid" and the company will not ship to my PO Box?
