November 13

This Friday is the U.S. Postal Service's recommended deadline to send holiday packages via Parcel Post to military personnel overseas. 

You've got a few weeks more–generally 'til December 4 or December 11–to send packages to civilians overseas using the less-costly Parcel Post. And if you're willing to spend the money for Express Mail, you can wait 'til up to a week before Christmas, even later to certain destinations like Mexico and the Caribbean.
