# Detect unauthorized sellers of your products

Lists every seller offering your product on Amazon and eBay and flags any not on your authorized reseller list, with their price relative to MAP. The sellers view groups offers by seller so you can see who is diverting stock and how much of the market they hold.

**Run it:** [Detect unauthorized sellers of your products on Apify](https://apify.com/fayoussef/map-violation-monitor/examples/unauthorized-seller-detection?fpr=youssef&fp_sid=abe_ex_unauthorized-seller-detection)  
**Actor:** [MAP Violation Monitor - Unauthorized Sellers & Price Cuts](https://automationbyexperts.com/apify/map-violation-monitor)  
**Pricing:** $0.015 per product checked
