The right price, on the retailer's page

What it shows
- A badge in the corner of the page: 🏆 lowest price, X% below average or discount not confirmed.
- The product's price history chart.
- The same product at other retailers, so you can compare before you buy.
- A button 🔔 alert me if it drops, which sends you a Telegram message when the price falls.

Your privacy
- The extension only looks at the product page of the retailers above and sends its address (and the price shown) to our server so we can respond. It doesn't read other tabs or keep your browsing history.
- It does not change links or inject affiliate cookies on retailer sites. Affiliate links only open when you click, with a notice.
- More details in the privacy policy.
A result only appears for products we already track. If we aren't tracking the product you opened yet, the extension lets you ask us to track it.
