give the gift of groceries

Commissary Gift Certificates are a fast, easy and convenient way for anyone, service member and civilian alike, to support our troops by “Giving the Gift of Groceries”, which can be redeemed at any commissary.
Commissary Gift Certificates can be purchased by either:

Ordering for A Special Patron
Ordering is a considerate way to personally give an authorized patron a commissary gift certificate.
Donating to Support Our Troops
If you don't know a specific service member, donating to your choice of one of five non-profit organizations is an ideal way to support our troops.

This is great. I wish that instead of donating, they'd just come home but, at least we can try to help as much as we can until that day comes

Thanks so much for your thoughtfulness in posting this. Our Troops need all the support they can get.
