insurance woes...

I've been writing on my other blog about insurance woes. Having to get child insurance for an auto policy is a pain. There are a ton of sites out there that offer online insurance quotes, and some advertise that they'll give you quotes from other companies so you can compare the rates. Not true in North Carolina, though. Why? Does anyone out there know why those sites don't quote several companies at once like they say they do? I know what the disclaimer says, but what's the real reason?
