Our default bid mode is Silent + Max Bidding, and in general, the one we recommend using. However there are other bid modes available, detailed below:
Silent Auction: standard incremental bidding
Silent + Max Bidding: standard incremental bidding with the additional option for guests to enter a Max Bid (the highest amount they would be willing to pay) and the system will bid for them to that amount.
Buy It Now: allows you to sell a set quantity of items at a fixed price.
Sealed Bidding: allows guests to enter anonymous bids without knowing what the top bid is. The highest bids win depending on the quantity set. To learn more about Sealed Bidding, see Sealed Bidding
