Each voucher has its own conditions (expiration date, limitations, etc.); you can check them by going to Profile > Vouchers and tapping on the voucher.
Vouchers must be applied during the purchase process, before the final payment confirmation. If the voucher cannot be applied to your chosen experience, you will not be able to select it (you will see it under "Vouchers not available").
You will be able to see a complete breakdown of your purchase on the final confirmation page, including the price of the selected ticket(s) and the discount applied (if any). We suggest you review this information carefully before confirming the purchase in order to avoid unforeseen charges; the final amount displayed will be charged in your selected payment method.
