When applying promo codes to an order, the code must be entered in the field labeled "Enter promo code", under the ticket price, during checkout. You must apply the promo code to your order using the "+" icon.
The discount can be viewed against your order before confirming your purchase.
NOTE: Each promo code correlates with a specific ticket type or order type, so not all promo codes can be applied to an order. Promo codes cannot be retroactively applied to an order once it has been processed.
