There is also Marys Natural Foods in Springdale. They have some really good snacks as well as the Ozark Natural Foods store in Fayettville. You might want to take a moment or two and look over the following page and it may help you fill in any questions you have about this type of allergy.

As for ideas on what to snack on how about bannana chips and dried apricots mmmmmmm, loved them as a child and loves them still. There really are alternatives out there that not only make up for not being allowed to eat the nuts but keeps you from thinking about the fact your not eating them as well. Good luck knows it wont be easy but is sure you can handle it.
Bblessed always in all things.
