eBay sellers with numerous item listings may encounter issues with duplicate item listings. Often unintentionally, items may be listed (or relisted) more than once which is against eBay's listing policy. eBay's policy states:
"To ensure buyers see a wide variety of options from a variety of sellers, we don't allow more than one fixed price listing of an identical item at the same time, from the same seller"
Sellers can check for duplicate item listings using a tool called "Duplicate Listing Scanner for eBay Items" located here. This is a FREE third-party tool that has proven helpful to myself, a Top-Rated eBay seller with nearly 20 years experience.
