Good afternoon ! I have one problem with the service charge. I need remove automatically from some product service charge. For example i have 2 product: Salads and Hookah. Price salad $ 10 and the price of hookah 50.
Total should reach: (10 + (service charge 10% from salad)) + 50 hookah without service charge = 60.10
I found in the forum but did not understand.
Thank you in advance
