Thousands of men and women in the nation's military and diplomatic corps are serving abroad during the holidays.

The Postal Service offers a reduced price of $17.40 on its largest Priority Mail Flat Rate Box for mail sent to APO/FPO/DPO destinations worldwide - a $1.50 discount from the regular price. The Postal Service is expected to process more than 16.2 million pounds of mail for these destinations this holiday season.

To ensure timely delivery, the Postal Service recommends that cards and packages be sent to APO/FPO/DPO addresses overseas no later Dec. 11 for cards, letters and priority mail packages and Dec. 18 for priority mail express military service, available to most destinations.

Free military boxes and supplies are available. The Postal Service has created a free military care kit based on the items most frequently requested by military families. The kit contains address labels, tape, boxes and customs forms. To order the kit, call 800-610-8734. To order flat-rate boxes featuring the "America Supports You" logo, go to usps.com/freeboxes.
