Hi Tom,
A form 1508 is not a merely a form that they choose to have on hand. It is a required form that they
will have, as per the
Postal Inspection Service. You might drop the hint the next time you visit your Post Office. It is a one page form that can be downloaded from their
Point of Sale Primary computer. Tell them to get it from
"Form Fill". (Postal language) it may make them wonder how you know this.
