Buy or Bid

buy or bid

In our BUY-or-BID sale, you never pay more than the Buy price.

- The sale starts at 4PM EDT (Amsterdam 22.00) and lasts seven days, during which time you can purchase an item at the Buy price and the sale for this item has closed.
- If you do not wish to pay the Buy price, you may bid lower.
- The BidAsk spread defines the gap between the minimum acceptable Bid and the items' Ask (buy) price.
- Items that have received bids within the BidAsk spread are sold at the highest bid after the sale's closing.
- We use proxy bidding, so you never pay more than the minimum necessary to remain a high bidder.
- Paulus swaen always clearly indicates which bidder placed the highest or winning bid.
- There are eight Buy-or-Bid sales per year. [See the agenda for 2024)
- An extensive list of FAQ and Answer pages are found here.
