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

There are eight Buy or Bid sales per year. [See the agenda for 2023)

  • Items will be listed for eight days in the Buy-or-Bid Catalog.
  • In the first 24 hours of the sale, users can only add items to their My Buy or Bid Watch List.
  • The next day you may purchase an item at the Buy price any time, and the sale for this item has closed.
  • If you do not wish to pay the Buy price, you may also bid lower on any item.

  • The "BidAsk spread" defines the gap between the minimum acceptable Bid and the Ask (buy) price of the items. A format successfully used on the stock exchange.  [Learn more]
  • 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. [Learn more]

  • For items that have received bids below the BidAsk spread, our sellers have two hours after the closing on whether to accept such bids. Generally, such bids are not accepted, and the item remains unsold.
  • If the seller matches the below BidAsk bid, the bidder is under no obligation, and he can cancel his initial bid at the latest within 24 hours after the closing, or the item is automatically added to the invoice.

  • An 18% commission (21,8% for EU customers) will be added to the invoice, plus the shipping fee.
  • Unsold items are no longer available after the closing.

What is proxy bidding?
For bids entered within the BidAsk spread, we use the proxy-bidding process. Our system will act as your bidding agent by entering your bid competitively against other bidders.
- You don’t have to worry about sitting at your computer to track the bidding process until the closing.
- You can bid the maximum price you would be willing to pay for an item.
- If there are no other bidders on a lot, the winning bid is always reduced to the lowest amount shown in the BidAsk spread.
- If another bid comes, the software will place a new bid following the bid increment every time someone else places a higher bid than you and will continue to do that until the sale ends and you win or the price goes over your set maximum.
-Proxy bidding takes the stress out of the bidding process; your maximum bid is always confidential, and you are getting the item at the lowest possible price

My buy-or-bid Watch List
You can monitor the buying and bidding status in one convenient place: My buy-or-bid Watch List. Item Watch

Labels are used to show the Buy or Bid status :
These are samples for an item listed at a Buy price of $ 500 and a BidAsk Spread of $400-500

  • Your Bid: $500 Sold to you
    When you pay the Buy price of $ 500, the item is immediately sold to you, and the sale for this item is closed.
  • Your Bid: $400 Accepted
    The BidAsk spread ($400-$500) shows the range between the minimal accepted price and the Buy price. When you place a bid within the spread, your bid is automatically accepted by the seller, but the items only sell to you if no higher bid is received or the Buy price is paid prior to the closing.
  • Your Bid: $350 High BidBelow Spread
    When your bid is below the BidAsk spread, and you are the high bid holder, the items only sell to you if the seller decides to accept your offer within 2 hours after the closing.
  • Your Bid: $50 Below Spread
    When your bid is below the BidAsk spread, sellers usually do not accept bids below the BidAsk Spread. Increase your bid to be successful.
  • Your Bid: $450 Outbid
    When your bid has been outbid by another user, increase your bid to be successful.
  • Your Bid: $250 High Bid I do not want this item
    When you have made a bid below the BidAsk spread, and the seller accepted such a bid. The bidder can delete his initial bid by hitting the "Cancel purchase of this item" button.
    Cancellations of such an accepted bid must be made at the latest 24 hours after the closing, or the item is automatically added to your invoice.
In short, your label has to stay green to be successful.

After the closing
  • In case you have placed bids below the BidAsk spread, you have to check within 2 to 24 hours after closing the status of your bids in My Buy-or-Bid Watch ListItem Watch
  • The invoice is available 2 hours after the closing of the sale.
  • When ready, go to the invoice & certificate section to download/print certificates and pay the invoice.
