This makes it a solid choice for individuals looking to minimize their balance transfer costs and focus on paying off their debts quickly.

Citi Diamond Preferred

The Citi Diamond Preferred card also offers a 0% introductory APR for 21 months on balance transfers and 12 months on purchases. This card is particularly attractive for its flexibility in setting up automatic payments on any date, which can help align payments with paychecks. However, the balance transfer fee is higher at 5% or $5, whichever is greater. Despite this, the Citi Diamond Preferred does offer additional perks such as free access to the user's FICO score and special access to purchase tickets for various events through Citi Entertainment. This card is ideal for users who want a longer period of interest-free payments and are willing to pay a higher balance transfer fee for additional benefits.
