Hi Apart from introductory discount is there some way by which we can offer discount to users?
Example : Say he has cancelled the subscription and his subscription is about to expire then offer him 45% discount on prices?
Solution : We can create another discounted subscription group that would have same subscription but for a lesser price. The only issue with this plan is that it may happen that a user get subscribed to two subscription gp. Also the original transaction Id changes so it will be hard to manage serve side.
