Pirates Booty is another favorite. I can find a 6 pack of small bags which is perfect for work at Amazon for as low as $17.85 with amazons subscribe and save.
Another to die for Gluten Free food is Kind Bars. So far my favorite is the Dark Chocolate Cherry Cashew bar it is like eating a candy bar. Some stores sell these in singles like QFC, Fred Meyers, Kroger, Costco, and Bartells. You can on Occasion find them on sale and if not then amazon is your go to for these bars.
Just remember that going gluten free does mean an increase in the price of the foods you eat but it also means that you will be having food longer. That is what I keep in mind when I look at the price. I also upped my fruit and veggie intake. Being Gluten free does not mean the end of the world it means changing how you see it.
