You can redeem your rewards via your McD BRAVO Rewards account! At the top of the page in your account, you will see the total amount of Rewards credit you have on file. Click on the monetary amount and you will be taken to the Gift Card marketplace. From there, you can select the gift card you would like to purchase and add a certain amount of credit.
Once you have completed your purchase, the gift card will be stored within the "My Orders" section of your account. You will have the option of printing the gift card or storing the electronic gift card on your phone. The gift cards can be used either online or in-store.
