The on-base grocery store has more benefits to shopping than you think. Active duty, Guard, Reserves, military retirees, Medal of Honor recipients, and dependents are all permitted to shop at the commissary by using their government issued ID. One advantage to shopping at the commissary is that each one is required to have a baseline savings average of 23.7% compared to civilian counterparts. Large-scale sales occur in the spring and fall, and coupons are available online. Numerous payment methods are also accepted, such as WIC, TANF, American Red Cross Disbursing Orders, and Military Star card.
