The idea behind the store was to allow special need students to gain hands-on experience handling money as well as dealing with customers. Eventually, the store started selling more than just pencils and paper. Cookies were introduced. After learning that another school had sold Otis Spunkmeyer cookies, a call was placed by WRHS transition coordinator Kak Eli-Schnieder to check it out. Soon after the call, the Supply Shack began selling cookies during the lunch periods.
Students bake the cookies every day.
They are then carted up to the Supply Shack where they are sold during every lunch period. Due to a limited number of cookies able to be baked in one day, the cookies often run dry at the store by the time the last lunch period eats. The cookies are sold off a computer-based system. Now, Washburn Rural leads the state of Kansas in cookie sales, including all grocery stores, gas stations and other schools. That is about 65,000 cookies in one single school year.
