Where do I enter my discount code?
If the event you are purchasing for has given you a promo code to use for a discount on your purchase, this will be entered on the final checkout screen where you see the total price of your purchase the fields for your credit card information. Simply type or copy-and-paste the promo code you've been given into the box and click the button Submit button. When a valid code is entered the discount will automatically be applied to your order total on the screen.
Additionally, some events will have enabled a "Social Discount." This feature offers you a discount for sharing the event on Facebook or Twitter. When enabled this option appears on the right-hand side of the screen. Click either the Facebook or Twitter icon, log in if necessary, and press the Share/Tweet button to see the discount immediately applied to your order's total price.
