Due to the Logistical difficulties and the higher costs for service
 associated with the U.S. Mail, We do not offer  it as one of our standard
 shipping options. We may impose an additional  handling fee on orders
 where the customer specifies U.S. Mail, or at our  discretion, cancel the
 order and refund the customer. Shipments going to overseas 
Military Bases will not be assessed extra charges.
