Not sure what to do with your expired coupons?  Send them overseas too the U.S. Military Troops. 

Our military families are limited to doing their shopping for groceries and household items at the Commissaries and Post Exchanges on base, where prices are much more expensive than you will find in our stores in the U.S. Both the Commissaries and Post Exchanges allow the use of manufacturer's coupons up to 6 months past their expiration date. In other words, a coupon with the expiration date of January 31st can be used overseas until July 31st. Our military families who are stationed overseas do not have easy access to the Sunday newspapers like we do here, so they are very appreciative of any coupons that are sent their way.
