Sealed Bid Auction FAQs


bidadoo Sealed Bid Auctions allow you to easily source and bid on items from featured consignors in a simple sealed bid auction format. A sealed bid auction works by submitting a bid to the auctioneer for the maximum price you are willing to pay for an auction item. Once bidding closes, all bids for the auction item are tallied and the person with the highest bid will be awarded the item. Bid amounts are only known to the auctioneer and are not known to other bidders.
