Hey Mark,
I am also looking into how to apply these kind of discounts. Pro Support forum suggest creating a custom add-on to do this. I don’t have the technical know-how myself but it looks as if it’s the only option available at this time.
Here is a link to the thread – https://wp-events-plugin.com/support/questions/discounts-to-mulitple-ticket-purchases/
I’ll let you know if I find any way to do this. Have you had any luck so far?
