If your PTO program pays to ship your Box Tops like ours does, you might want to consider this little tip to save some money.

Some official Box Tops are printed on corrugated cardboard. Often these Box Tops are submitted whole, with the Box Top printed on the top sheet of corrugated cardboard, corrugation in the middle and a bottom sheet of cardboard paper. (See example in photo to the right.) Huggies diaper boxes are the most common Box Top participant with this type of Box Top. And if you're school is like ours, it's one of the Top 3 submitted Box Tops each year. (Look for Box Top code HMD.)
However, if you gently peel away the corrugation you can remove only the Box Top layer from the cardboard. The corrugation is lightly glued at each ridge and will make a popping sound as you peel it away. It's almost as fun to do as popping bubble wrap, once you do it a time or two.
Removing the extra corrugation will save you on shipping cost. You won't be paying to ship more than two times the weight of the Box Top to send in corrugation and a bottom sheet of cardboard paper, both of which earn you nothing.
