Selling cookies is a major fund-raising activity of the Girl Scouts association. Prizes are offered to the girl who can sell the most. The cookies cannot be bought online, as the selling and interaction with the customer are deemed to be part of the development and experience for the girls involved. The sale of Girl Scout cookies began in the USA with homemade sugar cookies; now several large commercial bakeries produce the cookies. There are set varieties, and the different types have become famous across the United States.
