My bank said the account and routing info
was no godd. Apparently he is printing his own checks.

With computers, color printers and copiers readily available these
days, it's a growing risk.

RULE NO 1 : *NEVER* ship an item till the check or money order
clears. Even if it's a bank or postal MO.

My personal practice - cash postal MO' at the post office. Walk out
with cash in hand.

Other MO's - we wait till my bank clears 'em.
