WASHINGTON -- The Postal Service says Valentine cards for service members overseas need to be mailed by Saturday to be sure of getting them delivered by February 14th.
The Defense Department requires that mail be addressed to individual service members.
Military units are assigned an APO or FPO ZIP Code and in many cases that ZIP Code travels with the unit. APO/FPO mail is sent on special charter flights, commercial airlines and military service aircraft.
People who can't get to the post office can order cards sent by the post office via http://www-dot-usps-dot-com/ cardstore.
