I had A LOT of coupons that expired on March 31 that I didn't use. I don't have to feel bad about throwing these away anymore, thanks to Shelby at Shelby Making Cents who emailed me to let me know that military families stationed overseas can use coupons up to 6 months past their expiration date!
The Happy Housewife started a program in 2008 to benefit our families stationed abroad. If you go to her site here, it will give more details but basically you are assigned a family by emailing her and then you send your newly expired coupons to that family. It is just like mailing a regular mail envelope since mailing to a military APO address is considered a domestic address. What a great way to help our troops and their families!
