Eshop themes

I am interested in purchasing Eshop, I have a client using the current version in catalogue mode so I checked it over, there don't seem to be any themes like in the documentation eshopdocs.joomservices.com/plugins-and-t...theme-for-your-store which shows a dropdown with other themes, all I see is Default.
Where do I get these themes?

Also when I display the cart module it doesn't look like the demo which is a bit strange as surely if I buy it it should look like the demo?

Please explain how to make the cart module look like the demo using my current site template.

Demo and Current version images attached.

Andrew
