Add an expiration date
- This will allow the discount to be applied until a specific date.
- You can find availability/expiration date in the settings tab of the discount product
Trigger the Discount
- Triggers allow you to automate actions in the system. In this case, triggering the discount to add automatically.
- If you'd like everyone to have the early bird discount until the expiration date, trigger the discount to add automatically to everyone when their account is created, and ensure the expiration date is in place.
