In order to sell goods, shops need to be located where people can get to them easily. They need a large sphere of influence that guarantees a steady flow of customers and increasing profit. Building large shopping centres near good transport routes and motorway junctions can help. Shoppers frequently come in cars and out-of-town shopping centres or retail parks can offer large, free car parks, eg Cribbs Causeway near Bristol, Bluewater in Kent and the Trafford Centre in Manchester.
Advantages of out-of-town shopping centres
More accessible than city centres, which are often congested.
Large, free car parks.
Larger stores - meaning there is a good range of products benefiting from economies of scale.
Indoor shopping malls - so not affected by the weather.
Purpose-built shopping and leisure experience with cafes, bowling alleys and cinemas.
Disadvantages of out-of-town shopping centres
Create more traffic, especially at weekends and bank holidays.
City centres lose trade because people go to the out-of-town shopping centres.
