Loyalty programs (LPs) have flourished as they were easy to implement and gave immediate sales boost. From early eighties the literature has brought to light many positive cases of running LPs. Due to research, loyal consumers tend to buy only the products from one firm and give positive word-of mouth to other customers. In mid-nineties however, researchers discovered that there is no simple link between Customer's loyalty and his/her profitability. Foreign publications prove that basic benefits from maintaining customers may be false, as loyal customers are not more profitable that transactional, they are more sensitive to price and rarely are a source for recommendation.
