I have created a Tax Free Customer Group, so when a customer logged in, the price should be displayed without tax. And this is working find on a clean Magento installation.
When I implement this on my live site, all prices are displayed with tax. It simply ignored my Tax Free Customer Group.
I have the following code to display price, which is the same code as in a clean Magento installation.
Any reason why this code doesn't take customer group in consideration?
PS: I've also checked the admin, which is the same setup as in a clean Magento installation, where the tax free customer group worked.
