The Defense Commissary Agency (DeCA) Guard/Reserve On-Site Sales provide the commissary benefit to those who do not live near one. Customers shop and pay for purchases much like they would at a commissary. There are also preorder and prepay sales where customers order their groceries on-line and pay for them prior to pick-up at the designated location. There are also hybrid sales that are a combination of conventional and preorder/prepay. Sales average two or three days and are open to all authorized commissary shoppers. To find a sale, visit the DeCA Guard/Reserve webpage that lists sales locations and dates along with contacts for more information on particular events.
