Insurance switch?

We are really trying to get some of our expenses down around here. We are thinking of maybe changing our house insurance and looking for a better rate on our car too since we just paid it off. I just found a great wholesale insurance site that I think I am going to look into further. I have been with my auto insurance company for about 13 years though and when we have had accidents, they have been great, so the rate would definitely have to be a lot lower for me to switch.
