If I set up a subscription using a discount coupon but want to apply a different discount to the customer's next invoice, can I adjust the subscription with the second discount right after the first invoice has been processed?
For example, if I want the customer's first year subscription to be $0 and subsequent years to be $300 (the normal product price is $500), can I:
- Set up the subscription with a coupon for 100% off, and then, as soon as the first $0 invoice registers as processed,
- Adjust the subscription using a $200 off coupon?
Or must I wait a period of time to apply the subsequent coupon?
