Parcel post is the only means of shipping to an APO or FPO address. Due to size restrictions the maximum shipping box can be no larger than 72" width and girth combined. All military personnel must write or call to determine what size box will be used for the shipment. Once this is determined, OER^® will call or write to let you know if the order can be shipped by Parcel Post, and the correct amount required. All orders that exceed these limitations will be shipped in accordance with customer approval.
