This article describes the deceitful practices of catalogue companies that have also appeared in Slovakia. These kinds of companies sometimes advertise their products or services to be for free, whereas their paper forms state with small letters (sometimes on the back) that the form constitutes an irrevocable and chargeable order. The author mentioned that campaigns against catalogue companies had been organized all over Europe with state administrative bodies, consumer protection NGOs and the injured parties as participants. The article names different ways, which enable the injured party to avoid the duty to pay any of the demanded fees. It cites the UCP Directive and states that its Art. 6 Sec.1 letters a).b),c) about misleading practices with its corresponding Annex I is exactly the right legislative norm that will stop the spread of such companies.
