The text is focused primarily on the concept of informed consumers in the Czech law. In the beginning it describes general characteristics of the consumer information model, then it analyses pre-contractual information obligation and the demands focused on the transparency. As the position of the consumer is weaker than the position of entrepreneur, misleading commercial practices and unfair contract terms are examined as well. The text is then focused on sector specific rules, such as on the area of financial services and on the aspects of digital consumer including contracting, using cookies and reasonable consumer expectations. Throughout the text, some problematic aspects of Czech regulation or inappropriate implementation of European legislation are mentioned as well. The text then concludes (and it is trying to point out throughout the whole text), that the consumer could be overloaded by provided information. The aim of the chapter is to introduce national specifics within abovementioned areas and to analyse relevant questions of consumer protection connected with the topic of the informed consumer.
