The prices in overseas commissaries are significantly higher than those in the States and military families do not always have access to coupons in newspapers and inserts. Military commissaries overseas accept coupons up to six months past the expiration date.
The nice lady that runs the blog and the program is a military wife who spent time overseas and is now trying to help others. If you are interested go read her post, there is an email address at the end where you can request a family to send your expired coupons to. I am so excited I now have something to do with all my expired coupons!
