Is within a channel to demand money directions online through the USPS?
Answers:
Not according to the executive USPS site. They state that:
Domestic money advice may be purchased from:
a. All post office, branches, and stations contained by the United States and its territory and possessions.
b. Money charge services for member of the U.S. Armed Forces.
c. Rural route carrier and authorized highway contract route carrier. A customer fill out Form 6387 (available from the carrier) and give it and the fee to the haulier. Unless the customer provides a preaddressed envelope and pays postage and any required fees for mail, the shipper deliver the money demand on the subsequent trip.
