How does a timed online auction work?

A Timed online auction takes place entirely via the internet. You bid by automatic bidding. This means that you can enter a maximum bid for the relevant lot and the system will then bid for you until you are outbid. You can of course always increase your bid in the meantime. The system offers in steps of 5 euros. In case of two equal bids, the lot is awarded to the first bidder, but the other can always increase his bid.

The auctions are closed in stages. This means that 20 lots are closed every 5 minutes. When someone bids in the last 5 minutes, the auction of the relevant lot is extended to 5 minutes, so that the counterparty has enough time to make a higher bid.

You will receive an email if you are outbid, except in the last 15 minutes before closing.
