Girls will learn about on-line marketing and e-commerce by selling Thin Mints, Savannah Smiles and other cookies.

NEW YORK — Girl Scouts of the USA on Dec. 1 introduced Digital Cookie, which is designed to provide lessons about on-line marketing, app use and e-commerce to more than 1 million Girl Scouts.

Digital Cookie, a new addition to the Girl Scout Cookie Program, will allow customers to buy cookies through two separate digital sales platforms depending on the market area. For one platform, girls will invite customers via e-mail to visit their personalized cookie web sites. Customers may order from the web sites. For the other platform, girls will use a mobile app that allows for credit card processing and direct shipping.

The majority of the 112 Girl Scout councils nationwide are participating in Digital Cookie during the 2014-15 cookie season. Girl Scouts of the USA expects additional councils to join by the end of 2015.

“For almost a century, the Girl Scout Cookie Program has been teaching girls to be leaders in the world of business and finance, and we intend to ensure that legacy continues in the digital age,” said Anna Maria Chávez, chief executive officer of Girl Scouts of the USA. “Digital Cookie is a game-changer for Girl Scouts and a quantum leap forward in the evolution of the cookie program, coupling traditional sales activities with an on-line sales experience that teaches skills like on-line marketing and e-commerce, all in a digital space that puts an emphasis on learning, fun and safety.”
