**EltonCris**Since you are using regular fields as your products, you can only achieve coupons through condition and calculations.

You don't need to enter % in the calculation formula, you can use its decimal value. If the discount is user defined, simply divide the number by 100 to get its decimal value before deducting it from the total field.
