Description

Alerts when a competitor wins the Amazon buybox on your products. Buybox Monitor for Vendor is a companion to your Epinium account. It automatically checks your Amazon product pages and alerts you the moment a competitor wins the Buy Box on one of your listings — so you can react before losing sales. How it works • Sign in with your Epinium account. • The extension pulls your vendor catalog and checks each product's Buy Box across your marketplaces. • You get a clear list of the products where a competitor (not your brand or Amazon) currently holds the Buy Box, along with the winning seller. • Run a check on demand, or schedule an automatic daily check. • Export the results to CSV. Built for Amazon vendors who need to protect their Buy Box. Requires an Epinium account with the Buybox Monitor feature enabled.
