Each little Box Top for Education certificate you see on a grocery item translates to 10 cents for the Greenwood School. Please keep your eye out for them and continue saving them over the summer. We do several Box Top drives throughout the year and their values really add up. There's even a Box Tops app to increase your contributions. You can find these certificates on everything from Cheerios, Chex, and Ziploc bags to Annie's Mac and Cheese and Progresso soup.
