Dollar General, Family Dollar are in one class and Dollar stores are in a lower class.. I would be scared of eating anything from Dollar stores as from what I have observed the canned goods and packaged foods are from either overseas or no name brand, never heard of types. The Dollar General, Family Dollar types sell purposely downsize the items, less bang for the buck compared to Wal Mart or Kroger’s..
The Walmart GV brand is fairly good and about 1/3-1/2 less than name brand.
The Dollar store in my neighborhood sells name brands,Delmonte canned veggies, Campbell’s soup, Healthy Choice soup Heinz ketchup, name brand cereals to name a few.
