Flexible Web Design offers both Joomla+Virtumart Template and Virtuemart Template (aka. virtuemart theme). You should be aware what you are purchasing. There is big difference between them. Depends on your needs you should purchase the “correct” template.
1- Joomla+Virtuemart Template:
Example: https://www.flexiblewebdesign.com/Joomla-Virtuemart-Templates/SportMart
DEMO: http://demo.flexiblewebdesign.com/sportmart
It is a complete bundle package. It includes the Joomla Template + Virtuemart Template.
You don’t need any further template. Once you apply this template to your domain, you will get EXACTLY the same look as you see in the DEMO as if you are installing an ordinary Joomla Template. The only difference from the ordinary joomla template is that; your Virtuemart pages will also be styled (as you see in the DEMO)
2- Virtuemart Template (aka. virtuemart theme):
Example: https://www.flexiblewebdesign.com/Virtuemart-Templates/CleanMart
DEMO: http://demo.flexiblewebdesign.com/cleanmart/
Let’s say you are building your own custom Joomla Template OR purchased a Joomla Template from somewhere else (i.e: www.yootheme.com)
%99 of the Joomla Templates only stylize the Joomla pages, modules, menu navigation etc.. They don’t change the layouts of Virtuemart Pages (VM category page, VM product details page, VM shopping cart page etc..) simply because Joomla template developers don’t take into consideration the Virtuemart users. (The reason for that is; millions of people are using Joomla while only about 10k people are using Joomla with Virtuemart. “Law of supply and demand.”)
