[EX Q]: These bars are just the right balance between the flavor of the coconut & the sweetness of the rice syrup. Unfortunately, although the expiration date is in 2013, about a third of mine went bad, or perhaps started life that way. They had a funny, metallic taste, & one even had some black substance on it, which may or may not have been mold. I'm wondering if refrigerating would have prevented this. I highly recommend these bars, but beware of the keeping quality!

[EX Q]: These soy crisps are an excellent choice for snacking. With 7 grams of protein in each serving, they are SO much better for you than potato chips or other snack foods.They have a great flavor, just enough salt, and leave you feeling satisfied -nutritionally and snackwise ! My grandchildren know these crisps are what they will be offered at my house for snacking. I highly recommend them.
