If you're looking to stock up on Girl Scout Cookies for the year, Sunday is your deadline: Girl Scout Cookies sales end Sunday, March 11.

The Girl Scouts of Colorado estimate you need "at least 50 packages" to last you until next year.

If you are looking for cookies, use the “Cookie Locator” online or the mobile app to search for Booth Sale locations.

Sales of Girl Scout Cookies such as Thin Mints, Samoas, Tagalongs, Trefoils, Do-Si-Dos, Savannah Smiles, S’mores, Toffee-tastic and more help to support girls in developing five lifelong skills: goal-setting, decision-making, money management, people skills, and business ethics.
