Yes. All bids must be in whole increments. The bid increment can vary between auctions, but is typically either €500 or €1,000. You can always bid more than one increment above the current highest bid, but your bid amount must be a whole bid increment.
For example: Let's say you're bidding on a grader being auctioned, where the current highest bid is €60,000 and the bid increment is €1,000. You can successfully place a bid for €61,000, €62,000, €63,000, etc., but our auction system will NOT accept a bid of €61,500, €62,001, or any other amount which is NOT a whole increment of €1,000.
