The retail format influences the consumer's store choice and addresses the consumer's expectations. At its most basic level, a retail format is a simple marketplace, that is; a location where goods and services are exchanged. In some parts of the world, the retail sector is still dominated by small family-run stores, but large retail chains are increasingly dominating the sector, because they can exert considerable buying power and pass on the savings in the form of lower prices. Many of these large retail chains also produce their own private labels which compete alongside manufacturer brands. Considerable consolidation of retail stores has changed the retail landscape, transferring power away from wholesalers and into the hands of the large retail chains.
