This Citicard offers the longest zero-percent introductory period on the market at 18 months. While the zero-percent rate applies to both new transactions and balance transfers, the fact that it charges a 3 percent balance transfer fee makes it better suited for financing new purchases rather than borrowing to pay off older balances. This card does not charge an annual fee.
