I sold cookies as a Girl Scout and DD did also. I learned how to take orders, collect money, deliver cookies to correct person and pay for cookies. My daughter did also. As a leader I required girls to estimate cookies sold then see if they could sale that many. They usually under estimated. Our sale time started New Year's Day. We sold on that day as most Dads/men were home watching bowl games and bought more than women. Girls were not allowed to sale without adult supervision.
