Event add-ons can provide both extra revenue streams and extra opportunities for your attendees. For example if you wish to sell Event T-shirts or Wristbands on your event page, you can simply add extra add ons with your tickets along with price and quantity.
You can simply add this add ons section with your events tickets. To Apply this section on your event, you need to create event and after finishing event creation process, click on My store in top menu bar.
Now it's easy for customers to buy your extra add-ons while purchasing tickets.
