2.1. Consumer behaviour
Consumer behaviour is a field of study, which witnesses great attention from marketers. People buy things to satisfy various needs every day and make purchase decisions which affect not only themselves, but also their families, environment and most importantly, businesses which they buy the goods from. Therefore, it is essential to understand the way people buy and reasons for such purchases (Blythe, 2013). Moreover, businesses should be aware of the experience consumers get from purchase, which often affect future consumer acting. Thus, building customer loyalty is another aspect which should be clearly understood by business and in its importance goes hand in hand with understanding consumer behaviour.
Consumer behaviour is a process when people “select, purchase, use or dispose of a product, services, ideas or experiences to satisfy needs and desires” (Solomon, 2013, p. 31). Blackwell, Miniard & Engel (2001) define the consumer behaviour as a field of study focusing on consumer activities and analysing simply “why people buy”.
For this research consumption and post-consumption evaluation is relevant as these have an impact on brand loyalty. Consumers may be divided into three clusters according to the level of product consumption; heavy, moderate and light users. Simple rule stands here, heavy users display highest level of consumption and are known as a primary target market as most of profits comes selling to them and tend to be more loyal, which appears to be corroborated by what Geraghty (2007), when conducting a research on Irish alcohol market, found, i.e. people who consume beer more often tend to be also more loyal. Light users are quite the opposite and are likely to switch the brands more often. Moderate are in the middle of these two.
