The day of the corner shop is over, and they will eventually go the way of the bread delivery and milk delivery men. The supermarkets are managing to get a stranglehold on everthing.
Just look at what you can buy from these establishments now. Grocery, electrical goods, white goods, furniture, clothes, computers, Cd's in fact there is very little that you cant get from them.
As most of these supermarkets are owned by one group, what I forcast for the future is a time with no corner shops only supermarkets and these supermarkets will all be owned by one group, therefore there will be no competition and they will charge whatever they want.
