We want to have a promotion ( coupon ), The coupon will be applied to any purchase during the dates specified. But if it is 0% then it won't show on Invoice or checkout.
We want to have the coupon description and % value in case it was 0% or any number near 0 like 0.001% or 0.0001%.
Let say this way : if there is coupon in Invoice it should be printed or showed , regardless of value :
Thanks,
