How can I find items sold by a particular seller?
If you know a seller's user ID, you can search for items currently being sold by that seller. If you want to see the seller's ended listings, you can search for completed listings instead.
To search for items by seller:
Click the Advanced link at the top of the eBay home page.
Under the Items heading on the left side of the page, click By seller.
Enter the seller's user ID. If you're not sure of the seller's user ID, select the Show close and exact user ID matches option.
Tip: If you don't know the seller's user ID, try finding one item being sold by the seller. To display the seller's other items, click the See other items link in the seller information section on the right side of the listing.
