(36)In the case of distance contracts, the information requirements should be adapted to take into account the technical constraints of certain media, such as the restrictions on the number of characters on certain mobile telephone screens or the time constraint on television sales spots. In such cases the trader should comply with a minimum set of information requirements and refer the consumer to another source of information, for instance by providing a toll free telephone number or a hypertext link to a webpage of the trader where the relevant information is directly available and easily accessible. As to the requirement to inform the consumer of the cost of returning goods which by their nature cannot normally be returned by post, it will be considered to have been met, for example, if the trader specifies one carrier (for instance the one he assigned for the delivery of the good) and one price concerning the cost of returning the goods. Where the cost of returning the goods cannot reasonably be calculated in advance by the trader, for example because the trader does not offer to arrange for the return of the goods himself, the trader should provide a statement that such a cost will be payable, and that this cost may be high, along with a reasonable estimation of the maximum cost, which could be based on the cost of delivery to the consumer.
