Browser extension

Put Nancy in your browser

The extension watches for one thing: when you land on an Amazon product page that we already have a discount for, it tells you. That's the whole job.

What it does

• Flags a match. Open a product we're tracking and a small panel appears with the price we recorded and how much is off.
• Keeps the list a click away. The toolbar popup shows the current top deals, searchable, without leaving the page.
• Badges new catches. The icon shows a count when fresh deals land in your chosen departments.

What it doesn't do

It does not rewrite links you clicked yourself, redirect you silently, inject ads, or read pages outside Amazon product listings. Following a deal is always a deliberate click on your part — and when you do, that click goes through our affiliate link, which is how the site pays for itself.

Install it

1. Download the extension package and unzip it.
2. Open chrome://extensions and turn on Developer mode.
3. Choose Load unpacked and select the unzipped folder.

Once it's published you'll be able to install it from the Chrome Web Store in one click instead.
