I have an 8 yr old and an 11 yr old. I make them help! You want a candy bar find the coupon. My daughter (11 yr old) LOVES it! She finds coupons in the store and will take a handful.
It teaches them and helps me. I clip, sort and put them in my binder as much as possible. It's my hobby. I do this while watching tv. I try not to have more than I can get together by the next Sunday, that's always my goal. The coupon binder is a God send!
