  Stop Missing Out on the Best Deals!
  
  Are you tired of refreshing Facebook Marketplace, Kijiji, and Craigslist every 5 minutes just to find that the best items are already sold? Marketplace Monitor is your secret weapon to scoring the best deals before anyone else even sees them.
  
  Whether you are a professional flipper, a bargain hunter, or looking for that one specific piece of furniture, Marketplace Monitor automates the search process for you. Our extension runs in the background, scanning for new listings based on your custom keywords and price range, and alerts you the second a match is found.
  
  🚀 Key Features
  
  * **Multi-Platform Monitoring:** Track new listings across Facebook Marketplace, Kijiji, and Craigslist simultaneously from one dashboard.
  * **Instant Notifications:** Receive real-time desktop alerts or Telegram notifications the moment a new item is posted.
  * **Advanced Filtering:** Set specific keywords, price ceilings, and locations to ensure you only get alerts for items you actually want.
  * **Background Scanning:** Keep the monitor running while you work or browse other tabs.
  * **First-to-Message Advantage:** Click the notification to jump straight to the listing and be the first to message the seller.
  
  🛠 How It Works
