Hello All, I have a question please... I want to make a coupon to give to my existing clients so that they can get discounts on renewals for their existing products. How to do that? because the coupons are now applied to only new customers upon checkout. I want to do this because I have reseller hosting plan and I want to give clients discounts so that they can continue the services and not going to another competitor. Thank you all Your help is appreciated
