Promotion Code Without Deduct Shipping Fee


i try to purchase $ 3 cookies with $9 shipping fee, and my promo code is $ 10 discount.

possible to deduct the price without touching shipping fee?

mean that customer still need to pay the $9 shipping fee. the promo code only applied to total price of product purchase?

Thank You

I am afraid, you can use only Discount on all products in categories bonus and specify all categories for this bonus
