TonyCartoni — Price Radar for Any Store

Local. No sign-up. Carts and price history from Amazon, AliExpress, Temu and hundreds of other stores.

What you get: — Price history for every item in your cart — All your carts from every store — one click on the icon — Color indicator next to each item: green if the price dropped, red if it went up — Works right after install, nothing to set up — Full control: your data stays with you, you decide which sites get access — Free forever Where it works: Hundreds of online stores — from major marketplaces (Amazon, AliExpress, Temu) to smaller online shops. How it works: Just shop as usual. The extension automatically tracks items in your cart and watches prices in the background — nothing distracting, no popups. Privacy and permissions: The extension needs access to all sites — otherwise it can't work in the stores where you shop. But we don't abuse this: — Cart data is stored locally in your browser — We don't collect your browsing history — We don't share data with third parties — You can restrict access to just the sites you need — in Chrome's extension settings How to restrict: right-click the extension icon → "Manage extension" → "Site access" section → choose "On specific sites" and add only the stores you actually use. Don't see your store? Let us know — we'll add it in the next update. We regularly expand the list based on user requests. If you're curious: One day I noticed that the price in my cart had changed overnight — with no sale at all. It got me wondering how often this happens, but manually comparing prices across several stores every day is just too tedious — easier to forget and overpay. I wanted something that would do it on its own: you drop the same item into your carts on Amazon, AliExpress, Temu — and you just see where it's cheapest right now, without having to remember anything. That's how TonyCartoni came to be.
