About DeCA: The Defense Commissary Agency operates a worldwide chain of commissaries providing groceries to military personnel, retirees and their families in a safe and secure shopping environment. Authorized patrons purchase items at cost plus a 5-percent surcharge, which covers the costs of building new commissaries and modernizing existing ones. Shoppers save an average of more than 30 percent on their purchases compared to commercial prices - savings worth about $3,000 annually for a family of four. A core military family support element, and a valued part of military pay and benefits, commissaries contribute to family readiness, enhance the quality of life for America's military and their families, and help recruit and retain the best and brightest men and women to serve their country.
