Please, please, please do not throw your expired coupons away. They can be used up to 6 months after the expiration date printed on the coupons by U.S. military families living abroad (they cannot be used within the U.S., even in Alaska or Hawaii) through "Coups for Troops."
I've given the link with satellite location addresses here within the U.S. you can send your expired coupons to, so you and anyone reading this can mail them to the site of their choice, they in turn send them directly to a soldier's door. You also have the option to send them directly to a family through their direct mail program. I've also included the link telling you what coupons they CAN use.
FYI ~ coupons are just not available in places like Germany, England, Japan and Guam. I know this for a fact as a friend of mine has recently been stationed overseas and was horrified to find there's no coupons available like there is here in the states. So this is truly a blessing to our troops and their families and a great way to them our support.
