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)

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.

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

In short, your label has to stay green to be successful.
