If you do not want to show your entire shop from your homepage, but rather separate parts of it, eg a single product page, then simply follow these steps:

• Add this on to the end of your domain name: /index.php?option=com_virtuemart
  eg www.dotcomkiosk.com would be www.dotcomkiosk.com/index.php?option=com_virtuemart
• Preview the above and then as you navigate to a page you'd like to link to, copy the URL and use it
