To the Zagnut loving Violet B.,
Have we perhaps met over a tall glass of root beer at the Madison Cracker Barrel Old Country Store located next to Slumberland at 2147 E. Springs Dr., (608) 242-0560? There's a wider selection of candy there than on The Cracker Barrel Online Store.
I'd call over to that Cracker Barrel if experiencing a Zagnut zazzle. Or stop by any gas station, particularly your basic PDQ, to spin the sugar wheel. (The Dish will be doing a Gas Station Candy Review in mid to late October.)
To order online, glance over at the sidebar to your right. All the Online Candy Stores listed there carry the rare Zag nut.
I'll keep an eye out for you. Well, not literally.
Meanwhile, have a look around The Candy Wrapper Museum.
