Choose balance transfer deals carefully
It's possible to save money with balance transfers but there are also traps to avoid.
In most cases the low honeymoon transfer rate only applies to the transferred amount. New purchases are charged at the card's normal rate from the moment the transaction is made.
And, when a new credit card has been established with a balance transfer from another card, there may be no interest-free days on purchases until the card debt is paid out in full.
One pitfall to be very clear about is the rate you will pay on the remaining balance transferred once the introductory rate expires. With some cards this is the cash advance rate, which can be more than 20%.
