It is the changing taste and preference of the customer who has bought into a change in the market. The income level of people has changed. New generation of people are not more dependent in the haat market and distant department stores. Today we can see a new era in market with the opening of many department stores, hypermarket, stop buyers, malls, brand outlets and specialty stores. . My study is based on a survey of a hypermarket clients called big bazaar. Big bazaar is a new type of market that came into existence in India since 1994. It is owned by Pantaloon Retail India Ltd. It is a type of market where several types of products are available under one roof. My study is in determining the customers who buy the behavior of customers in Grand Bazaar and the level of customer satisfaction in Grand Bazaar.
