Received the email delivery gift card quickly. Provided instructions worked great for adding the gift card to me account. NOTE: It seems Disney will not split the bill of an annual subscription between my gift card balance and my credit card. Instead, it says it will bill the gift balance ($100) and gives the new date my subscription will end from it billing that amount. It seems to be the fair portion of the year the $100 covers, which is alright, but I may buy another gift card so I can pay in-full and keep it renewing at the same time each year.

Worked perfect for my monthly subscription! Added to my account and will let it work for the next few months.

Disney won't let me use this to buy a normal Disney subscription. Sam's Club support says that Disney says things are A-OK so they won't give me my money back. I guess credit card dispute is the next option.
