Join Box tops online and earn cash for your child’s school.  It’s easy and Free. Earn additional cash by clipping Box Tops from hundreds of participating products.  This is one of those things that takes literally a minute or two to register and then enter the box tops you are going to get with all your GM cereal at Jewel this week.  While each top is worth only a little, together they add up to new playground equipment or something similar.  It does work (I’ve checked it out).
