Each month, the Defense Commissary Agency (DeCA) brings Commissary products and prices to select locations away from their regular bricks and mortar stores. I'm not sure if it is my imagination, but it seems like the sales aren't being planned as far in advance as they were a few months ago.
I've just discovered several sales for the rest of April:
April 19 – 21 Coast Guard Base Astoria Sector Heli Hangar, 2185 SE 12th Place Warrenton, OR 97138 April 25 – 26 Camp Shelby Bldg. 2610 Camp Shelby, MS 39407 April 25 – 27 Camp Joseph T. Robinson Bldg 3000, Chappell Armory North Little Rock, AR 72199-9600 April 27 – 28 Guard and Reserve 4675 State Route 181 North Greenville, KY 42345 The links in these listings are to the sponsoring stores. Contact them to confirm details about dates, locations and times. Sometimes you can get lists of products and prices before you go to the sale. I really don't know if sequestration will affect future remote location sales. Overseas case lot sales have already been cancelled as the logistical costs are high.
