When bidding on items, there are two things you should keep in mind. First, every bid is binding. Even if you outbid yourself, the last bid you placed is valid. This is the only way we can ensure a fair auction process and meet the interests of both buyers and sellers. Secondly, in the special auction conditions of each auction you will find relevant contents. Find out about the general conditions of the auction at an early stage. If you have any questions, please do not hesitate to contact our Customer Care Team.
