CAVE CREEK — An Anthem Catholic returned from a trip to a local grocery store with far more than food. Chuck Filteau, who doesn't even  have children at nearby Annunciation Catholic School in Cave Creek, entered his name and the school into a Box Tops for Education contest.

Generally, the nationwide program coordinated through General Mills credits schools with money, ten cents at a time, for clipping out coupons from its products. Filteau and his wife, Emelda, have been sending such coupons to the school via their neighbors, who are grandparents at Annunciation.

This time, the Filteau's stewardship went 100,000 times farther. Weeks after his shopping trip, Filteau was shocked to learn that he won. The prize: $10,000 cash for the school.

Annunciation Catholic School, which currently serves fifth-grade students and younger, will receive the prize in December. It will fund various school needs.

Last year the Cave Creek school earned $653 and $400 the year before that. Schools nationwide earned some $59 million through the Box Tops program in the 2010-11 school year, the latest for which figures are available.
