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.
