[6] Schnucks is one of the largest privately held supermarket chains in the United States and dominates the St. Louis metro grocery market.

Schnucks underwent a major expansion in 1995 when it purchased from Loblaws the National Supermarkets chain (a total of 57 stores), also based in St. Louis.

The company's growth in the St. Louis area was bolstered by the local abandonment of two major supermarket chains: A&P in the 1970s, and Kroger in 1986.

This store, located at the corner of Ninth and Olive Streets in the central business district, was called "Culinaria – A Schnucks Market" and was advertised as a "new urban prototype".

The placement of the store reflects the downtown area's urban renewal of the 21st century, including Washington Avenue Loft District, St. Louis loft-style condominiums and apartments.

[15] In 2020/2021, Schnucks exited the Iowa/Quad Cities market with the closing of their Bettendorf, Iowa store and a pharmacy in Moline, Illinois (with the customers transferred to the stand-alone CVS as part of that acquisition).
