I don't understand what this is supposed to do. They say it saves you money. When I downloaded and tried to use it, it literally doesn't do anything. The extension is so poorly built that it can't even recognize an authenticated session within the browser - which means you can't use it for anything. I am using a fresh install of Firefox in a brand new install of Windows so it's not my cache, history, etc. as I have none.

Don't waste your time with this and ignore Capital One's claims and advertisements that they are better than Amazon (LMFAO). Capital one is a scrub compared to Amazon and this extension proves exactly that.
