Thank you for your answer, but I think we misunderstood each other.
Let me give you an example:
The product initially costs $50
The partner receives a 30% discount on the product. (i.e. the partner get $15 if no coupon is used)
If a customer uses a 10% coupon, the customer pays $45, and I would like the partner to receive a discount of $15 – $5, but in your case, the percentage for the partner is calculated from the amount discounted after the coupon , so he get 45$*0.3=13.5$
To sum up, is it possible in your plugin to make the commission for the partner count from the initial amount?
