See who's selling your product on Amazon and flag any seller not on your authorized reseller list. No agency retainer required. Unauthorized resellers and diverters can appear on your Amazon listings for weeks before you notice — usually when a customer complaint or a price crash tips you off. Enterprise brand-protection platforms catch this, but they're priced for brands doing real volume, often $2,000+/month. This extension gives you the lightweight version: maintain your own list of authorized resellers, then scan any Amazon product page to see which current sellers aren't on it. Features: One-click seller scan on any Amazon product page you're viewing Manual entry fallback when auto-detection doesn't catch a seller A running check log so you can spot patterns over time Pro: bulk CSV import of your authorized reseller list Honest note: this tool checks the page you're actively viewing — it doesn't continuously monitor your listings in the background, and "authorized" status is based entirely on the list you maintain. It's a detection aid, not automated enforcement.
