When asked about the current level of savings for commissary shoppers in an era of sweeping reforms, the interim director of Defense Commissary Agency (DeCA), retired Navy Rear Adm. Robert Bianchi, referred to results of a price comparison survey conducted in 2016 and released in late January last year. It showed average savings at commissaries “globally” were 23.7 percent compared to prices at commercial grocery stores. More specifically, patron savings averaged 20.2 percent at stateside commissaries and 44.2 percent overseas. For more details, see this Military.com article.
