Show the redemption screen with your offer to the merchant. Once the merchant has taken down the relevant information and has informed you that you will receive the discount, select the "Done" button. Once you select the "Done" button your offer will be marked as redeemed and you will no longer be able to use it, so make sure that you have received your discount. If you or the merchant has any questions about redeeming your offer, select the question mark icon at the lower right corner of the offer screen.
