Time is running out to send holiday packages to deployed Soldiers. Dec. 10 is the deadline for sending packages to most areas by Priority Mail and also for sending letters or cards by First Class Mail. After that, the only way to get it there in time for the holidays is by the premium Priority Mail Express Military Service (PMEMS). The deadline for PMEMS is Dec. 17 for most overseas locations. The deadlines are simply "to make sure people get it before Christmas." Another way to ensure timely delivery is by completing the online customs form before taking packages to the post office. The online customs form can be found at the U.S. Postal Service (USPS) website. For more on holiday shipping deadlines, see this Military.com article.
