Introductory offers
This feature allows you to create dynamic pricing configurations for various use cases. You can add one free trial and up to 2 discounted periods per pricing tier. The total offer duration must not exceed the standard plan period — so if your subscription plan duration is 7 days, the free trial and discounted periods combined cannot exceed 7 days.
For example, you can configure a price with a 3-day free trial and multiple pricing phases before the standard price of $8.99 is applied. And later that price could be shown in Paywall - New Block - Stripe Checkout Form.
The trial period can only have the same duration as the standard plan period, or less. If a trial is longer than the standard plan period, the system will create a subscription with the standard duration and charge the user unexpectedly at the end of this period.
