This paper deals with long term loyalty programmes of selective grocery retailers who operate in the market within the Czech Republic. Only those loyalty programmes designed for the end customers are taken into account, so this study is concerned with the B2C area. A long term loyalty programmes last at least for one year, i.e. twelve months (this time determination is valid for purposes of this paper). The main aim of this paper is to identify the single elements and principles occurring in long term loyalty programmes and then to develop an illustrative model. The presented output is a model of long term loyalty programmes that captures the three following phases: the establishment, development (or building) and termination of the relationship. In addition, from the empirical research, an interesting fact has emerged: two of the analysed long term loyalty programmes were launched at a similar time. This could be explained through the tendency for companies to copy the successful activities insigated by their competitors. Furthermore, the next remarkable phenomenon is that one grocery chain runs two long term loyalty programmes at the same time and the target groups of these programmes overlap. A possible explanation could be that the chain is making eff orts to interest as many as possible of its diff erent customers.
