Citibank has been promoting an interest free credit extension with a 3 % initial fee that is linked to your credit card. The outstanding balance displays on your credit card statement. This is similar to Home Depot 's credit card offer, but at Home Depot it is truly interest free and at Citibank it is not. At Citibank, if you continue to use your credit card for monthly purchases that are paid off within the billing cycle you get charged interest within the billing cycle for new purchases. If I had not participated in the interest free credit extension, I would not pay interest charges on new monthly purchases paid off within the billing cycle. I made the full payment of new credit card purchases, and was still charged interest. At Home Depot you can use your credit card ( without interest ) as long as you make the minimum monthly payment. Citibank is conducting false advertising by claiming this offer is interest free. It is not interest free.
