I have adopted an Army base in Grafenwoehr, Germany. I send expired and unwanted to coupons to them. The commissary on base will accept coupons up to 6 months expired. They do not have access to coupons that come in the mail so they rely on us to send the coupons to them. Through our monthly coupon exchange and my friends and family we have donated over $57,000 worth of coupons. I mail out the coupons monthly. If you have expired or unwanted coupons and want to donate to the base contact me.
I am working with the Overseas Coupon Program. Check out their website. If you are able to adopt your own base to send coupons to.
