Now that you've polished off the Christmas cookies . . . it's time for Girl Scout cookies. The 2010 campaign kicks off Saturday and extends through the end of March. Along with old-time favorites - Thin Mints, Tagalongs, Samoas, Do-Si-Dos, Trefoils, Lemon Chalet Cremes and Dulce de Leche cookies - this year's featured cookie is the Thank U Berry Munch, a complicated little number filled with dried cranberries, crisp rice and white fudge chips. A 6-ounce box containing 14 cookies is $3.50 from a Girl Scout near you.
