Convenience stores and supermarkets are sprouting all across the capital city of Delhi in anticipation of the retail boom. It has been estimated that there will be a supermarket for every half-mile in the city by 2010 when the Commonwealth Games will take place. A few years ago there were only 5 supermarkets per half-mile in 2004. Customers are switching to these modern for the all the conveniences they offer such as long shopping hours that suit most working professionals and central air-conditioning.
