Get correct price with reductions

[sanl]

Hello, 

 

I have 2 customers groups: default and wholesale_group. In wholesale_group I have group discount 30% for all products.

 

And If I would like to do clearance or special product discount I always do discount for only customers (default group). So If retail price <= wholesale group price, wholesale_group clients should see retail price with reduction not with group reduction.

 

I tryed to do it in classess/product.php, but I couldn`t get price with reduction to compare: 

if dealer {
   if (retailprice <= wholesale_group_price) {
     $ price = $price - specific reduction }
  else {
$price = $price  - $group-reduction
}

Should I do it in product.php file or i must do it in product.js file?
