Looks really good!

One thing I've noticed from using it. If you try it without logging in and click the "Upgrade Now" button, it doesn't do anything and fails with:

dev_index_1421847173.min.js:2 Uncaught TypeError: Cannot read property 'email' of undefined

It seems that it's trying to check if my email is "[email protected]".
