Hotel Canary is an extension that helps you find hotel deals. It works with priceline.com. When you are navigating the express deals section, Hotel Canary displays a little popup with the list of hotels that match all the criteria of the deal. That helps you decide fast if you want to take the deal! To use it after installation, just choose your deal and click on the extension icon on the right top corner of the browser. NOTE: Mac users need to click on the deal first, and once the new window opens, click on the bell icon to reveal the list of hotels.
