A search for all the items that a member of eBay has placed bids on. This feature lets you see what items you've bid on during the last 30 days. Although you can use search by bidder to view your own current auctions or history, eBay recommends you use My eBay instead. My eBay has many more functions to manage your bidding and buying activities.You can also use this feature to see what another member has bid on during the last 30 days. All you need is the member's User ID . To protect bidder privacy, not all items that this member has bid on may be displayed. To keep eBay a safe place for buyers and sellers, members cannot view or search for member-specific information – such as User IDs – on the Bid History page. The Bidding Details page contains detailed information on bidders; however, all bidders are assigned anonymous names – such as Bidder 1. Only the seller of the item can see a bidder's User ID. See Managing Buyers and Bidders for more information on managing bidders.
