Go here to sign up for a $10 coupon booklet from Box Tops for Education. Usually Box Top For Education label products include Betty Crocker, Pillsbury, General Mills, etc.
The be sure to turn in the Box Top labels to your child's school (or pass them on to someone who will use them for their school). Each label is worth $0.10 and they add up quickly. My children's school is in quite a competition to see which class can collect the most! It's an easy way to help support your local school.
