By default, Virtuemart uses its internal shopper groups for doing things like assigning prices and restricting access to certain products.
The problem with this is that ONLY Virtuemart uses its own shopper groups, so if you have other extensions like RSMembership which change the normal Joomla user group of a user, Virtuemart has no idea.
So if someone buys a subscription in RSMembership, and you drop that user into a "Premium" usergroup, and you want Virtuemart to give them a price discount for being in that "Premium" user group, it doesn't appear to be possible since Virtuemart uses its own shopper groups, not the normal Joomla user group.
Is there a solution to this problem or some setting/modification to Virtuemart that makes it utilize the Joomla user groups, rather than its shopper groups?
