Sure. Let's say I have a $100/mo product (subscription) but I want to offer a recurring 20% discount via a coupon. It seems that when I apply the coupon during purchase, it applies the 20% discount to the initial $100 payment, but not to the future payments so that the discount covers the life of the subscription.
Here's an example. I created a 100% off coupon. It applies the coupon to the initial purchase but not to the renewal. How can I have a discount that applies for the length of the subscription (until the member cancels the paid membership)?
