Grandma Gayla Casebolt of Mt. Home, Arkansas took Baxter Healthcare by storm with her Girl Scout Cookie sales. Yep, Gayla & Madison Shipman created their brand. Gayla & Madison started it last year with this letter. Gayla made copies of the letter and included it with every order. People went nuts over it. This year they hunted her down to buy cookies from Madison. Guess Grandma’s Marketing Plan Worked!
