When you are logged in to your Yesty account and click on the Keuzekaart, you can choose "Choose a gift card" at the bottom of the page. Then the selection of gift cards will appear for you to choose from. Once you have made a choice, click on the relevant store/website and use the green button "Choose this gift card". If you want to proceed, click on "Exchange Gift Card". NOTE! You can no longer go back to another Gift Card once you have done this. The chosen Gift Card with its corresponding code will appear in your account, and you can start using it.
