Hot air popper. I pop a bag to take to school and munch on. On game nights, keeps the girls happy so I don't have to feed the vending machine or concession stand.
I keep a container of presweetened drink mix and plastic cups in the car, Keeps us from stopping and paying for drinks while out. We either get free water at McDonalds, or free from a park fountain. On long trips I take 2 or 3 kinds of drinks, as well as a jug of water in the coolor iwth other things to eat.
Cell phone. Everything from here is long distance. With the cell, its all free.
