How do you start a Casey's general store franchise?

Answer 1

You don't. Casey's used to franchise but not anymore:

Franchise Operations

In the early days of Casey's existence, the Company offered private investors the opportunity to establish franchised Casey's stores as a way to expand the Casey's system at a rapid pace. The franchise owner ("franchisee") was authorized to construct a Casey's General Store according to the Company's plans and specifications and to operate the store in accordance with the Company's franchise agreement. Although each franchise store displayed the name and trademark of Casey's, it was independently owned and operated by the franchisee. The largest number of stores owned by any one franchisee was thirteen. The first franchised Casey's store opened on July 1, 1970 in Waukee, Iowa. In the ensuing years, the increase in franchise stores almost equaled the growth of company stores. As of April 30, 1985, the Casey's chain of 482 stores included 232 franchise stores.

The Company discontinued active Franchising in the mid-1980's, though a few new franchise stores were built after 1990. However, the total number of franchise stores began to decline in the late 1980's, as some franchisees took advantage of opportunities to sell or lease their stores to the Company. By January 1, 2000, there were 145 remaining franchise stores, compared to 1,084 company stores. The Company then began buying existing convenience stores as a primary means of growth, and purchased many of its franchisees' stores during the early 2000s. A few franchise stores were sold to other owners or operated independently after their franchise agreements expired. By November 30, 2007, only 15 franchise stores remained. The last remaining franchise store, in Prophetstown, Illinois, closed on December 31, 2008, thus closing an important chapter in the history of Casey's growth to 1,478 stores at April 30, 2009.
