The good news is, it's Girl Scout cookie season! The bad news is, it's the last year for two of the varieties. How to stock up and keep them fresh.

Girl Scouts across much of the Mid-Atlantic region have already started their annual cookie sales. And if you’re a fan of some of the most recent flavor releases, you’ll want to stop by those grocery-store booths and Walmart storefronts soon.

Girl Scout cookie sales officially started Jan. 7. See this year's flavors, which ones are planned to go away, and how to buy online.
