At this time, we are not able to apply discounts to the purchase of Special Event Registrations. If you would like to see this added to Altru in a future release, please like this idea in our community. Our Product Management team uses a variety of methods to determine new features in Altru and ideas in the Community is one way they do this, so your vote helps Product Management prioritize the new features that we put into the product.
