A mall experiment by CBC News suggests that all it takes to get your credit card rate lowered is a phone call and a question. They approached 10 mall shoppers and had them dial their credit card company, and told the shoppers to say this: "I think I've been a good customer. I'd like to stay with you, but I really want you to lower the rate on my card. Can you help me?" They were advised to ask for a supervisor and say the same thing if the customer service rep told them no. Six of the 10 were able to get their rates reduced! Three of the shoppers quoted in the article report they were offered new rates that are about half as much as their old ones. You have nothing to lose by calling, so why not take five minutes and try?
