General Public: Retail Price.

Hello,

Thanks for your reply, I have the Business and I can set prices for two different groups.

Now my cultural issue is that for a user group to display the price without taxes on the display of products but at checkout and the other group members that prices are displayed both on screen and in the product summary purchase.

How should I configure it?

Thanks

Hi,

So you have to set the taxes option to show both. Then edit the view "product / listing_price" and get the user group, then depending on the user group change dynamically the value of the option for the taxes.
Add code like the following one at the top of that view:

$user = JFactory::getUser();
$groups = $user->get('groups');
if(in_array('8',$groups))
	$this->params->set('price_with_tax',0);
