Before purchase, a voucher's Redemption Instructions will be listed on the voucher's page itself, below the Fine Print section.
After a voucher is purchased, you can check for its Redemption Instructions by going to your Fave app > ME > My Vouchers. When you click on the voucher you wish to check on, scroll down to the Redemption Instructions section. You will be able to find further information on how you may redeem your voucher, and other information you may need in order to utilize your voucher (e.g., Partner's contact information, details to provide to our Partner, etc.)
