+1 on the LDS. If you have an LDS friend ask them to find out when their church is planning a canning trip to the "bishop's storehouse". Its in slidell, la for this area. You may can go in with their church group and be able to purchase several types of dry goods, including wheat, in bulk or canned in the one gallon cans - at wholesale without taxes. I've done this and its worth it.
