I have this site where customers are split into different groups each giving a different percentage discount (10%, 15%,20% and 50%)
The problem is I also have some products that are on discount too. For example it has a discount of 20%
What happens now is that normal customers who are not in any groups will get the 20%
But customers that are in the group will get additional discounts so they are receiving a discount of 30%,35%,40% and 70% which is wrong.
I want the customers in my groups to just enjoy the 20% offer.
Can any help me with this?
