It's possible to add add-ons both at the checkout and in the MyOrder environment of the fan. Fans will see upsell options at the checkout when they have added products to their shopping cart.
In the MyOrder environment, fans can personalize tickets, resell tickets, change names, and of course, download their tickets. Fans are in this environment at different times, making it the perfect place to make add-on products visible.
