(28)In order to avoid administrative burden being placed on traders, Member States may decide not to apply this Directive where goods or services of a minor value are sold off-premises. The monetary threshold should be established at a sufficiently low level as to exclude only purchases of small significance. Member States should be allowed to define this value in their national legislation provided that it does not exceed EUR 50. Where two or more contracts with related subjects are concluded at the same time by the consumer, the total cost thereof should be taken into account for the purpose of applying this threshold.
