Consumer’s behaviour is often studied because certain decisions are significantly affected by their behaviour or expected actions. For this reason consumer behaviour is said to be applied discipline.In a general sense, the most important reason for studying consumer behaviour is the significant role it plays in our lives. Much of our time is spent directly in the market place, eating or engaging in other activities. A large amount of additional time is spent thinking about products and services, talking to friends about them, and seeing or hearing advertisements about them. These general concerns alone are enough to justify our study of consumer behaviour. However, many seek to understand the behaviour of consumers for what are thought to be more immediate and tangible reasons. The main reason behind this project was to find out the buying behaviour of the consumer while shopping at big bazaar because most of the population surveyed preferred to shop at malls and how day by day the consumers demands are increasing and through this project I came to know that what are the various behaviour of a typical customer who shops at big bazaar.
