Malls promote competition and serve consumers well  Hypermarkets and malls promote competition and so serve consumers well. Because of their huge purchasing power and economies of scale, large retail chains with huge outlets such as Wal-Mart, Tescos and Carrefour can offer products much more cheaply than smaller high-street rivals. The convenience and greater enjoyment offered by out of town malls can also push urban shopping centres into improving their own provision for consumers. This can be seen through improvements in the urban environment, better policing, cheaper parking and more ease of access, and the provision of entertainment and special events (e.g. farmers markets, foreign markets and street festivals) to draw shoppers in from a wider area. The public have voted with their feet, in 2003 48% of everything bought in Britain was bought in out of town stores1.  1 Watkins, M. (2003, June 27).
