With more than 300 stores in small towns and on highways in New Mexico and West Texas, Lonnie and Barbara Allsup have long been recognized as innovators in the industry since opening their first location in 1956, then known as "Lonnie's Drive in Grocery" in Roswell,. N.M. Often cited as the "mother and father of the modern day convenience store," they were one of the first to offer 24-hour self-service gasoline and were early innovators selling cooked foods from burritos to barbecue. Allsup's stores are known for their deep-fried burritos and eggrolls, made fresh at the stores.

As an early adopter of technology, Barbara oversaw the development of Allsup's proprietary point of sale and price-book technology in the early 1990s. In addition to their c-store chain, the Allsups own a petroleum jobbership, a software development company, radio stations and world championship cutting-horse ranches in Texas and New Mexico. Allsup's sells fuel under the FINA, ConocoPhillips, Exxon and Allsup's private-label On the Go brand
