Here's a link to a news piece that the CBC Marketplace program here in Canada broadcast awhile ago though I can't seem to find the video link. What they did was have some shoppers at a Winnipeg mall call their credit card company and read a script asking for them to reduce their interest rate because they've been good customers and are seeing other cards offering much lower rates and may switch. In nearly all cases the people got their card rates dropped substantially all from a simple phone call.
In a similar vein I called my auto insurance asking for a reduction in my motorcycle insurance and in less than 5 minutes on the phone my premium was cut in half.
