The United States Department of Defense operates almost 236 commissaries worldwide for the benefit of US military families through DECA, the Defense Commissary Agency. The aggregate sales of all commissaries combined is approximately $5 billion annually. DeCA’s principal mission is to provide discounted fresh fruits and vegetables, groceries, and household items, to active-duty military, retired military, members of the Guard and the Reserve, and their families. On average, US military commissaries save participating military families 25% on food and household goods that they routinely purchase for everyday living. This helps military families improve their standard of living and, thereby, improves morale and performance of the military itself.
