Q: I would like certain people with particular email domains to be able to register for $0, but I don't want to use Access Code for hidden free tickets? 

A: In order to satisfy your requirement, we suggest to setup as follows:

1. Leave the ticket available in public

2. Create new promo code, type is Registration Discount , no code needed

3. Discount amount: Overwrite the price of Total Amount to S$0

4. Applies if:  

- Attendee email contains the required domains

Note: if you have more email domains, Criteria Pattern = (1 or 2)  would be (1 or 2 or 3 or 4 or 5.....) 

5. Applies to:

- The available ticket
