Can you get a lower Interest credit card rate?

Dear TerrieCredit Card Accountability, Responsibility and Disclosure Act of 2009, or Credit CARD Act, might provide some help. It requires issuers to review rate increases imposed on or after Jan. 1, 2009, every six months and reduce the rate if the reason for the increase has improved. This evaluation is supposed to be done automatically, with no action necessary from the consumer. No specific amount of reduction is required, however. An exception to that is if a 60-day delinquency triggered the rate hike. In that case, the increase must terminate within six months if the cardholder makes at least the minimum payment on time during that period.
Do your research first by comparing your current interest rate to the APRs on credit card offers for new customers. When you call customer service, politely ask for a better interest rate on your credit card. You may want to provide a few reasons why you deserve a break, such as the number of years you've been a customer, how frequently you use the card, your solid payment history or that you are considering a balance transfer to a competitor's card with a lower interest rate.
A blemished record could result in not only a denied request, but a negative change to your account, such as a credit limit reduction. The plan may not work, for instance, if you already have the lowest interest rate, hold a credit card with subprime terms or carry a large balance. If the issuer refuses to give you a lower APR, ask the reason.
