Standard Subscription - Customer buys a subscription, they get a subscription code, and they then use that code to make reservations online or at the box office.
UPDATE: You can activate the subscription on the ticket level under the pricing template area now for both assigned seating events and on general admission events.
UPDATE: "How it works" can now be overridden on a per subscription level. Just click the gear next to the subscription and select "how it works" from the drop-down menu.
