@@kymation i've installed the price module. I have the same problem as @@katapofatico above. It won't show the discounted price, it just shows the old price and the new one is always 0,00. I tried to fix it with the code above but i don't understand exactly what i need to do because i'm not that handy with php.
here's the error:
Notice: Undefined variable: new_price in D:\Program files\xampp\htdocs\responsive\includes\modules\content\product_info\cm_pi_price.php on line 41
