If you know someone serving in the military overseas, November 12th is the earliest deadline at the postal service to get holiday packages to them for the cheapest price.
Only the US Post Office ships to APO and FPO addresses.
All military mail is sent by domestic mail rate, but has earlier deadlines than domestic mail.
The post office also offers military care kits.
For more information on those, call 1-800-610-8734.
