The drugstore market in Croatia has been very competitive and very active in terms of marketing for many years. There are several larger drugstores in Croatia, each of which emphasizes one segment of activity and focuses on a certain group of people and due to the wide and various assortment, the number of their customers is extremely large. Likewise, many customers decide to shop in several different drugstores for similar or the same products with different benefits, so it is significantly more difficult to maitain a loyal customer base and constantly attract new customers. The research on the satisfaction of drugstore customers is focused on the reasons why they are loyal to a certain brand or a specific chain of drugstores. Iti s very interesting that this is influenced by the attitude of the sales staff towards the customers, the price, marketing tools, benefits when purchasing and of course the loyalty program and similar reasons. In the same way, each of the drugstores on the Croatian market has a parto f products and/or services that other chain drugstores do not have in their assortment, and thus at least in a certain moment they encourage satisfaction among some groups of customers. Iti s very interesting that some research has already been carried out, which examines the satisfaction of drugstore customers and the elements that influence the creation of that satisfaction. During the research conducted for the purpose of writing this thesis, the results obtained indicate that customers in Croatia, mostly women, buy the most in dm-drogerie markt chains and their decision to buy is influenced by the breadth of the assortment and the proximity of the point of sale.
