The story
The original concept was established by Lonnie and Barbara Allsup in Roswell, New Mexico, in 1956, as Lonnie's Drive-In Grocery. Lonnie, a veteran of the United States Air Force who served in the Korean War, expanded the business into a small chain and sold it to 7-Eleven in 1963. With the earnings of that sale, the Allsup family relocated to Clovis, New Mexico, and began the Allsup's convenience store chain.
Allsup's is known for being the first company to introduce self-serve gas pumps. It is ranked as New Mexico's #1 privately owned corporation, and is the largest convenience store chain in the state.
The original founder, Lonnie Allsup, died in January 2018.
