Supporting Girl Scouts of Eastern Iowa and Western Illinois

Girl Scouts builds girls of courage, confidence, and character who make the world a better place.

100% of proceeds from One Tough Cookie benefit Girl Scouts, so yes, that does mean cookies are involved. Girl Scouts aren't just about cookies though. They're go-getters, innovators, risk-takers, and leaders who take action when there's a problem, have the confidence to take the lead in their community, and are constantly coming up with new ideas to make the world a better place.
