Am I able to transfer an unused gift certificate over to a new recipient, without canceling the transaction?
You may edit the gift certificate by navigating to the Gift Certificates section of your Order Management System and clicking on the blue pencil, and assign it to a new recipient by changing the recipient name and email fields. Click finish. Back on the main Gift Certificates screen, if you change the status to unsent, note that the old "send date" will be removed, and the gift certificate will de-activate. Changing status back to Sent will send the new gift certificate email to the new recipient's email, and re-activate the gift certificate.
