I have Group Pricing Per Item installed, and all is going well.

But I have a 5.00 product that I want to be free for all members of Group A.

I have it set up the same as my other products -- with 5.00 as the regular price, and 0.00 as Group A Price (Net) and Group A Price (Gross)

But the $5.00 is still showing up for the Group A customers.

I think it's interpreting the "0.00" as meaning there is no Group Price available for Group A, rather than it being Free, maybe?

Is there a way to fix this, so that Group A can have the price as free - truly 0.00?
