Track e-commerce product prices and get notified when they go on sale. Stop manually checking prices. Let Sentinel do it for you. Sentinel tracks the prices of products you care about across any online store — every single day. When a price drops or a sale starts, you'll get an email notification so you can act fast. How it works: 1. Browse to any product page and click the Sentinel icon to start tracking it. 2. Sentinel checks the price daily and builds a price history over time. 3. When the product goes on sale, you get notified by email. Features: - One-click tracking — Add any product to your watchlist directly from the product page. - Price history — See how a product's price has changed over time with built-in sparkline charts. - Daily monitoring — Every tracked product is checked automatically, every day. - Sale alerts — Get an email the moment a tracked product goes on sale. - Dashboard — Manage all your tracked products from the extension's side panel without leaving your current tab. - Works everywhere — Supports products from ANY e-commerce site. Free to use. Create an account at sentinel.sale to get started.
