Shelby Coffey, 10, and her sister, Madalyn, 7, sell lemonade in front of their home on Tuesday afternoon at the intersection of Wayne and Cherry streets in Celina. Their mother said the sale had raised more than $50, and the sisters plan to donate part of the profit to a children's or cancer treatment hospital and set aside money for college. Due to the strong response, the girls plan more sales, she said.
