(24)A public auction implies that traders and consumers attend or are given the possibility to attend the auction in person. The goods or services are offered by the trader to the consumer through a bidding procedure authorised by law in some Member States, to offer goods or services at public sale. The successful bidder is bound to purchase the goods or services. The use of online platforms for auction purposes which are at the disposal of consumers and traders should not be considered as a public auction within the meaning of this Directive.
