Saving a dime (or 5,000 dimes) in '09

On Regis and Kelly a few weeks ago they had a segment about saving money. One of their suggestions was to check your car insurance rates, then check other companies and see if you could get a better deal elsewhere. Then they suggested you call your company and see if they could beat the other rates. Does that make sense? So Dan and I had insurance through a company which shall not be named but which claims to save customers 15% and has annoying commercials. I looked into a few different companies and found that we could save $500 a year by switching to another company which shall not be named but also has annoying commercials. Our current company couldn't make our rate any lower so we switched! $500! And our new company promised to plant a tree since we paid online. Just wanted to throw that suggestion out their for anyone who might find it useful. (If you want the actual names of the companies, email me. I just don't want to get in trouble for some unforseeable and stupid reason!)
