Box Tops for Education

My kids' schools participate in a program where you collect the little stamp-looking "Box Tops" off of food packages.  The schools use them to purchase supplies; each is worth 10 cents.  The schools send home papers to attach the Box Tops to, 10 at a time.  We have been collecting them all summer.  Tonight, it was I who received the education.  After discovering I have collected almost enough to fill a whole sheet from one product alone - butter, I have now been educated on why I am a fat kid.  Somehow I don't think that was what they were going for...... =(
