Include different price discounts for your Theater Seating

To enable this you'll want to turn on Offer Seating Price Discount. You'll find this on the Event Settings screen under Event Page Options. You'll need to have Seating Chart turned on. 

After this setting has been turned on you should see a new tab on the Event Setup screen titled Seating Price Discounts. Here you can add as many discounts as you'd like for either a Percent or Amount off. 

On the event itself when an event attendee goes to select a seat they will have the option to select what type of seat they are getting.

Please note that you must have Theater Seating to utilize this feature.
