Overview

Gemco was an American membership department-store chain that combined discount general merchandise with supermarket-style grocery retailing. Established in Anaheim, California, in October 1959, it became part of Lucky Stores the following year. Lucky, a California supermarket company based in San Leandro, expanded Gemco into a larger regional chain and used the format to provide members with a broad one-stop shopping experience. Stores typically brought together groceries, clothing, home goods, garden supplies, seasonal merchandise, consumer products, and selected concession businesses under one roof. In this respect, Gemco was an early example of the large-format retail model that later became widely associated with hypermarkets and warehouse-style discount stores. The chain's membership proposition was central to its identity. Customers used membership cards, received recurring promotional material through the Gemco Courier catalog, and could access services intended to make large shopping trips more convenient. One distinctive practice involved holding purchased groceries while members continued shopping elsewhere in the store. A numbered plastic card linked the customer's cart or carts to the stored groceries, which could then be retrieved and loaded into the customer's vehicle at a designated area. Gemco also operated a credit department and used concessionaires for services such as gasoline and jewelry. Some locations experimented with free child supervision, but the trial was discontinued after regulatory requirements made the arrangement impractical. Gemco's visual identity changed over time. Its early stores used brown exteriors with tan accents and red lettering. During the late 1960s and 1970s, the logo was commonly presented as translucent serif capital letters inside a dark-blue horizontal oval. In the early 1980s, the exterior palette shifted toward blue with lighter blue accents, while the logo used white lettering and a yellow diamond above the letter M. The name was selected because it was short and easy to remember; despite later speculation, it was not an acronym. Lucky also operated the related Memco banner in markets where the Gemco name could have been confused with an existing local chain called GEM. Memco stores served parts of the Washington, D.C., Baltimore, Richmond, Chicago, and North Carolina markets at different times. Memco membership cards were interchangeable with Gemco cards, although the stores used their own blue-oriented branding. Several Memco markets struggled, leading to conversions or liquidations during the 1970s and early 1980s. Gemco remained commercially healthy for more than two decades, but its parent company later faced unsuccessful leveraged takeover attempts. To reduce exposure to those pressures and concentrate on its broader business, Lucky decided to liquidate Gemco. The final liquidation took place from September through November 1986, ending the chain's operations. Many former West Coast Gemco locations were subsequently leased or sold to Target, helping Target expand into California. Target remodeled a number of the sites and opened stores in most of the former Gemco locations by fall 1987. Gemco is therefore remembered both as an early membership hypermarket operator and as a predecessor whose real estate contributed to Target's West Coast growth.

History

Gemco began in Anaheim, California, in October 1959. It was created as a membership-oriented department store, but its format extended beyond conventional general merchandise by incorporating groceries and other high-frequency shopping categories. The concept anticipated later hypermarkets by attempting to combine supermarket convenience with the breadth of a discount department store. A Gemco customer could purchase food, apparel, household goods, garden merchandise, and other products during one visit, while also using selected services and concessions located in or around the store. Lucky Stores acquired Gemco in 1960. The California supermarket operator supplied the capital and operating structure needed to turn the initial business into a regional chain. Gemco's membership model supported repeat visits and allowed the company to communicate directly with shoppers through membership cards, catalogs, and promotional materials. The Gemco Courier, a monthly member publication, used illustrated covers and carried retail advertising and merchandise information. The chain also maintained a credit department, which was particularly active during the Christmas shopping season. The stores developed a number of service features intended to reduce the inconvenience of large shopping trips. In one distinctive system, members could leave purchased groceries with the store while continuing to shop. A numbered plastic card identified the stored goods, and staff retrieved and loaded the groceries into the member's vehicle when the customer was ready to leave. Gemco also used outside concessionaires for gasoline and jewelry. A small number of stores tested free babysitting, but the service was stopped after approximately a year when California licensing and insurance requirements made the arrangement unsuitable for the operation. Gemco's identity evolved visually. Early buildings prominently used brown and tan colors, with red lettering. Later designs employed a dark-blue oval logo with translucent serif letters. An early-1980s redesign adopted blue exterior surfaces, light-blue accents, white logo lettering, and a yellow diamond above the M. The name itself was chosen for memorability and pronunciation rather than as an abbreviation. The company also established the Gemco Charitable and Scholarship Foundation in 1959. The foundation organized school-based competitions and awarded scholarships to selected high-school seniors in communities served by the chain. Lucky used the Memco name for stores in territories where Gemco could have been confused with an existing chain called GEM. Memco stores opened in the Washington metropolitan area in August 1970 and later reached Baltimore, Richmond, and other nearby communities. The banner also operated in the Chicago suburbs, where stores opened in Niles and Arlington Heights in 1972 and Lombard in 1973. The Chicago locations did not perform well and were converted to Eagle Family Centers in 1977. Memco briefly entered North Carolina in 1980, opening stores in Winston-Salem and Greensboro, but those locations were liquidated by early 1982 as Lucky concentrated on other Memco markets. The Washington-area Memco business also contracted. When Lucky announced its withdrawal in December 1982, the market had thirteen operating stores and another under construction. The stores were liquidated by March 1983, leaving approximately 1,200 retail workers without jobs according to the cited historical account. Many of the former sites were subsequently occupied by other retailers, including Bradlees, Home Depot, and Kmart at different locations and periods. Gemco itself continued operating into the mid-1980s. Its decline was linked not to a single product failure but to financial and strategic pressure on Lucky Stores. After a series of unsuccessful leveraged takeover attempts directed at the parent company, Lucky concluded that liquidating Gemco was the preferred way to respond to the situation. The final liquidation ran from September to November 1986, bringing the chain's operating history to an end. The disposal of Gemco's real estate had consequences beyond the brand. Target acquired or leased many prime former Gemco locations on the West Coast and opened remodeled stores in most of them by fall 1987. These sites helped Target establish a stronger presence in California. Gemco consequently occupies a transitional place in American retail history: it was an early membership hypermarket and a large-format retailer whose stores, services, and later real-estate portfolio foreshadowed the growth of modern discount superstores.
