Sure, some cards offer 0% APR balance transfers for 15 months. The rules for these cards are the same as for all other 0% balance transfer cards.
During the promotional period, you must at least make the minimum payment on the statement by the due date.
To eliminate the debt before the promotional period ends, you will have to pay more than the minimum each month.
At the end of the introductory period, you should have paid off the balance transferred to the card. If you don’t, the interest rate on the card immediately jumps to the regular rate for the remaining balance.
