A larger commercial zone can be found in many cities, more formally called a central business district, but more commonly called "downtown" in the United States, or in Arab cities, souks. Shopping hubs, or shopping centers, are collections of stores; that is a grouping of several businesses.

A shopping hub or centre, is a collection of retail, entertainment and service stores designed to serve products and services to the surrounding region. Traditionally, shopping hubs were called bazaars or marketplaces which were generally an assortment of stalls lining streets selling a large variety of goods. The modern shopping centre is now different from its antecedents, the stores are commonly in individual buildings or compressed into one large structure (Mall). The first modern shopping mall was The Country Club Plaza in Kansas City which opened in 1922, from there the first enclosed mall was designed by Victor Gruen and opened in 1956 as Southdale Centre in Edina, Minnesota, a suburb of Minneapolis. Malls peaked in America in the 1980s-1990s when many larger malls (more than 37,000 sq m in size) were built, attracting consumers from within a 32 km radius with their luxurious department stores. There are different types of malls around the world, the Superregional malls are very large malls that contain at least five department stores and 300 shops, this mall can appeal to a broad radius (up to a 160-km). A regional mall can contain at least two department stores or "anchor stores". The smaller malls are often called open-air strip centres or mini-marts and are typically attached to a grocery store or supermarket. The smaller malls are less likely to include the same features of a large mall such as an indoor concourse, but are beginning to evolve to become enclosed to comply with all weather and customer preferences.

Stores are divided into multiple categories of stores which sell a selected set of goods or services. Usually they are tiered by target demographics based on the disposable income of the shopper. They can be tiered from cheap to pricey.

Yet another approach is to collect data is through crowdsourcing. This lets the price comparison engine collect data from almost any source without the complexities of building a crawler or the logistics of setting up data feeds at the expense of lower coverage comprehensiveness. Sites that use this method rely on visitors contributing pricing data. Unlike discussion forums, which also collect visitor input, price comparison sites that use this method combine data with related inputs and add it to the main database though collaborative filtering, artificial intelligence, or human labor. Data contributors may be rewarded for the effort through prizes, cash, or other social incentives. Wishabi, a Canadian-based price comparison site, is one example that employs this technique in addition to the others mentioned.

However, some combination of these two approaches is most frequently used. Some search engines are starting to blend information from standard feeds with information from sites where product stock-keeping units (SKUs) are unavailable.

Some retailers sell "tokens" as an alternative to coins, often for charity. Merchandising companies also offer branded shopping tokens as a product.

In some airports a system similar to the shopping cart deposit is also used with luggage carts as a profit making opportunity. Companies like Smarte Carte charge two or more dollars (U.S.) (or equivalent) for rental, and return a small token reward of a quarter (25 ¢) for returning carts to the other end of any dispenser machine.
