When you successfully claim an e-gift card you will receive and email with a link to your e-gift card. Please note that when you click on the gift card link it should take you to a page with your e-gift card. All you would need to do is print the page.
If this is not your experience, please make sure to try different browsers on a desktop or laptop. First try directly clicking on the link on the email. If this does not work, copy the link on the email and paste it on the browser.
