Price Chopper is a group of four separate family-owned chains of grocery stores formed in 1979 in the Kansas City and Des Moines metropolitan areas that share a common brand name and unified marketing campaigns.
 The owners are the Ball, Cosentino, McKeever, and Queen families in Kansas City and DGS Foods in Des Moines.
 All ownership groups are members of Associated Wholesale Grocers (AWG), which allows Price Chopper to have the buying power of large chains and to share marketing costs.
 The five ownership groups own and operate 55 stores across Kansas, Missouri, and Iowa.
 Slogans for the chain include "Just Right" and "Fresher Ways to Save".
 Price Chopper is the number one grocery store chain in the Kansas City metropolitan area in terms of both sales and number of stores.
 Its biggest competitor in both Kansas City and Des Moines is Hy-Vee.
Festival Foods is a privately owned company operating stores throughout Wisconsin.

IGA is a U.S. brand of grocery stores that operates in more than 30 countries.

 It was founded in the United States as the Independent Grocers Alliance.
 The headquarters is in Chicago, Illinois.
 IPA is also owned by IGA in Ontario Canada.
A health food store is a type of grocery store that primarily sells health foods, organic foods, local produce, and often nutritional supplements. Health food stores typically offer a wider or more specialized selection of foods than conventional grocery stores for their customers, for example athletes and bodybuilders, people with special dietary needs, such as people who are allergic to the gluten in wheat or some other substance, or have diabetes mellitus, and for people who observe vegetarian, vegan, raw food, organic, or other alternative diets.
Colonial Stores were chain grocery stores once found throughout the South.
 Most were transformed to Big Star Markets in the 1970s (later Harris Teeter and The Great Atlantic and Pacific Tea Company).
 The chain evolved from Norfolk, Virginia's D.P. Pender grocery stores, and were known for a rooster logo.
 It is one of a handful of regional grocery chains based in Norfolk, including Giant Open Air and Be-Lo Food Stores.
Festival Foods is a family owned grocery store chain based in Minnesota (not to be confused with the Wisconsin store chain) and operates six stores in the Twin Cities.
 Festival Foods is owned and operated by sisters, Marie Aarthun and Lauri Youngquist.
 Their stores are located in Andover, Bloomington, Brooklyn Park, Hugo, Lexington and White Bear Lake.
 The stores in Andover and Hugo feature Dunn Bros in-store coffee houses that roast their beans fresh on-site.
 The chain also contains other special in-store offerings, such as a full selection liquor store in Hugo and a café at the Bloomington Location.

 Western Family Foods was established December 19, 1963.
 The company supplies independent grocery stores with store brands.
 It is based in Tigard, Oregon.
 It distributes the Western Family, Shurfine, Shursaving, MarketChoice and Better Buy brands which are used in many independently owned supermarkets. On June 13, 2016 Western Family Foods announced that they had been acquired by Topco and plans to close their Tigard office by the end of 2016.
The Petrini's market chain was established in San Francisco and run as a family owned business until 1989, when it was sold to a large corporation, Provigo.
 The markets were widely known for having the finest meat in the San Francisco area, and the marketing strategies employed at the stores are still an inspiration for grocers nationwide.
 At the beginning of the 20th century grocery stores were sometimes much like department stores with different partners owning and operating their own departments.
 The founder started out operating the meat section of Lick Market on 7th and Clement in 1935 under such a scheme.
 He opened three other markets within a few years of that time.
 The largest Petrini's grocery store was opened in 1956 on what is still known today as Petrini Plaza, near Fulton and Masonic in San Francisco.
 At the time of opening of that store, there were already four other large grocery stores in San Francisco.
 That original store was torn down and replaced by an apartment complex by the same name.
Buttrey Food & Drug was a chain of grocery stores founded in Havre, Montana and formerly headquartered in Great Falls, Montana.
 The company was founded in 1896 as a chain of department stores branded Buttrey Department Store.
 The company opened grocery stores in 1935 and sold off its department store division following a 1966 acquisition by grocery company The Jewel Companies, Inc. Jewel was sold to American Stores in 1984 and Buttrey was sold off as separate company in 1990.
 The company was sold to its main competitor, Boise, Idaho based Albertsons, in January 1998 and the Buttrey name was retired.
 At that time, Buttrey was operating 44 stores in Montana, Wyoming, and North Dakota with a revenue of US$391.4 million.
 As of today, most former Buttrey stores continue to operate under the Albertsons banner.
