DisneyGiftCard.com will be undergoing some important changes on January 20th. Any stored gift cards will be deleted along with your current log in and password. They will be allowing you to create a new account with the same Disney log in you use for other Disney sites.
Bottom line, if you have Disney gift cards stored in your Disney Gift Card website account, make sure you have the physical card or the full gift card details written down somewhere.
Here’s a link to the full statement Disney.
