I assume this is not the Disney VISA card as they have some special promotions for purchasing
DVC.
If it's another card, then be careful. Generally when you make a payment it applies 100% toward the balance with the lowest interest rate and the other balances accrue interest charges.
Example: You charge $10,000 at the 6.99% rate.
During the month, you charge an additional $500 as regular purchases.
You make a payment of $1000. ALL of the $1000 applies toward the $10,000 loan and none of it applies toward the $500 monthly charges. Those charges will accrue interest at whatever the cards' normal rate is. This could be anywhere from 17% or higher. That $500 will be charged interest each and every month until the original $10,000 is paid off in full.
Look at the fine print. If it says all payments are applied toward the lower interest rate balances first, then the above is what can happen.
You can still use the card, just be careful to put it away and not make any further charges on it until the original loan is paid off.
(the Disney Visa card has offered special incentives where they apply your payment to both your current regular balance and to your special loan balance. This is not typical for most CC's.)
