24Furthermore, it must be pointed out that only a commercial practice which is categorised beforehand as an invitation to purchase is covered by Article 7(4) of Directive 2005/29, whereas all commercial practices, including invitations to purchase, are subject to the requirements of Article 7(1), (2), (3) and (5) of that directive. An invitation to purchase, which is defined in Article 2(i) of that directive, must contain a number of key items of information, which are listed in Article 7(4) of the directive and which the consumer needs in order to take an informed transactional decision. In the absence of that information, which Article 7(4) describes as material, an invitation to purchase is deemed to be misleading and is therefore unfair, as is apparent from the provisions of Articles 5(4) and 7 of Directive 2005/29.
