Girl Scout Cookies season has arrived and hundreds of girls are eager to begin selling their treats this week. Despite the popularity of classic Thin Mints and Samoas, a new cookie, Savannah Smiles, has joined the ranks in 2012 to commemorate the 100th anniversary of the Scouts.

Savannah Smiles are described as bite-size, lemon-wedged cookies dusted with powdered sugar and bursting with zesty lemon flavor. The organization hopes this newest addition to the classic Girls Scouts' tradition will be a big hit this winter. The new cookies are named for the town of Savannah, Ga., where founder Juliette Gordon Low started the Girl Scouts back in 1912.

As hungry fans wait for their doorbells to ring, many have sought other means to find where they can buy Savannah Smiles and their other favorite winter treats.

The much-loved Girl Scout Cookies are not sold online as sales of the cookies continue to be a competition between the girls as part of the leadership experience program. The cookies can only be purchased from a Scout or from a Girl Scouts booth. The organization urges that any cookies found for sale online should not be purchased under any circumstances as they do not support the girls in the program.

Tech savvy cookie cravers can also use the new free mobile app to search cookie sales in their neighborhood. Download the Cookie Finder app for the iPhone to find Girls Scout Cookies near you. Cookie fans can also download the Locator app by calling **GSCOOKIES (**472665437) from their phones.

Customers who want to support the Girl Scouts, but are not interested in purchasing cookies,  can also buy boxes of cookies as a donation. The boxes are then used in community projects, known as gifts of caring, and may be given in food collections.

Approximately 70% of the proceeds of Girl Scout Cookies are given to the local Girl Scouts council, including the group directly selling the cookies. The remaining balance pays the two commercial bakers, ABC Bakers and Littler Brownie Bakers, for the cookies.

By participating in the Girl Scout Cookies sales, girls can earn awards, such as the cookie and financial literary badges or the annual Cookie Activity Pin. Girls can also win awards based on their sales activity, such as program credits or recognition items.

Cookie sales have started this week and will continue until March 18. Give a call to your local Girl Scouts council and buy some of your favorite cookies soon.
