This is a very poignant topic at the moment, often being mentioned in main stream news broadcasts. The vitality of town centres, economic growth, the external effects of the internet, all form topics of great interest. I never forget watching a young group of people window shopping in Cheltenham, they were examining training shoes. One person suddenly pulled out an i phone, scanned the bar code, and announced to the group that the same pair of shoes could be bought for less money on the internet. The order was duly placed, and the people left the shop.
