Big-box store

A big-box store (also supercenter, superstore, or megastore) is a physically large retail establishment, usually part of a chain. The term sometimes also refers, by extension, to the company that operates the store. The store may sell general dry goods, in which case it is a department store, or may be limited to a particular specialty (such establishments are often called "category killers") or may also sell groceries, in which case some countries (mostly in Europe) use the term hypermarket.

Typical architectural characteristics include the following:

Commercially, big-box stores can be broken down into two categories: general merchandise (examples include Walmart and Target), and specialty stores (such as Menards, Barnes & Noble, or Best Buy) which specialize in goods within a specific range, such as hardware, books, or consumer electronics respectively. In recent years, many traditional retailers—such as Tesco and Praktiker—have opened stores in the big-box-store format in an effort to compete with big-box chains, which are expanding internationally as their home markets reach maturity.

Labor unions oppose big-box development because the employees of such stores are usually not unionized. Unions are especially concerned about the grocery market because stores such as Kmart, Target, and Walmart now sell groceries. Unions and cities are attempting to use land-use ordinances to restrict these businesses.

Because it is generally inaccessible to pedestrians and often can only be reached by motor vehicles, the big-box store is regarded as unsustainable and a failure of urban planning.
