You can easily track your bid through two key areas:
View Your Bids Page
On this page, you’ll see all the bids you’ve placed, categorized into All Active, Outbid, Winning, Won, Lost, and Archived. Items on which you are the highest bidder will be clearly marked as "Winning," along with the current bid amount and basic details of the item.
Item's Full Page
You can also visit the full page of any item you’ve bid on to see if you are the current highest bidder. It will show a notification bar at the top indicating whether you are winning or have been outbid.
Additionally, the View Your Bids page includes a search bar, allowing you to quickly find specific items you’ve bid on. This helps you stay updated on the status of your bids and ensure you maintain your winning position.
What Happens When You Win an Item?
When you’ve won an item, you’ll receive an email notification with the details of your win. The item will also show up under your Open Orders page in your account, where you can review the purchase, complete any necessary payment, and follow up on shipping or pickup details.
