Casey’s General Store increased its estimated sales per unit by 22.2 percent across the latest and preceding years, outperforming its Top 100 c-store peers in that regard. It did that by improving in-store foodservice facilities, better promotions and refining its menu of pizzas, burgers and hot sandwiches, appetizers such as Buffalo wings, and doughnuts and baked goods, which it sells by the dozen. Casey’s is owned by Casey’s General Stores Inc.
