Customers sometimes become attached to the items sold by one seller. When a customer has bought one item from the seller, you might suggest other items the seller has for sale. You can make such suggestions using the SellerListingSearch operation.

The SellerListingSearch operation takes a seller ID and returns, potentially, all of the items offered by a seller.
