Looks really good. In fact I'm kind of envious, the base theme already looks better than what I was able to create using the same stack.

A couple of very minor things:

The buy now button has an alert attached to it.

The documentation is great, but it suggests that you have to create / install the plug-ins by yourself? If that's true it would put me off buying.

Hope that helps.

p.s It might be worth enabling the responsive features of bootstrap on the main site. It works well on the demo.
