Disney recently launched the Disney Vacation Account site, which allows you to go in and create a savings account to save for your next Disney vacation. You can create this account and contribute from your debit card, credit card (which seems to miss the point of a savings account, imo), or Disney Gift Card. You can track your earnings on the site. As long as your money is in there for 120 days, you are eligible for a $20 gift card for every $1000 saved. There are no fees.
I have to admit, I am not impressed. Although the 2% interest rate (in gift card) is higher than most online savings accounts (I use CapitalOne 360, but I have been meh since Capital One took over. Ally is also good), it’s a gift card. In general, I’m not sure this would work to encourage savings (and given you can use your credit card, I’m kind of scratching my head why it is good for budgeting–I’m not anti-credit card, I just..why?).
