To access the duplicate listings in your marketplace inventory that you have added to SellerRunning, visit the Inventory tab at the top of the homepage and click the Duplicate Listings tab.
This page lists the duplicate listings in your inventory. You can remove these listings in bulk by clicking the tab with the image below. Again, you can search your duplicated listings by ASIN, SKU, and Product Name.
For your Amazon Seller Account health, consider removing duplicate listings in your inventory at short-term intervals. Keeping such products in your inventory may cause price errors and may affect your account's health.
