I got quotes from nationwide (with whome I have a car, a truck and my house), state farm (who I shopped the above coverage to) Geicko and progressive. The last two I did their online quotes, and Progressive blew them all away....much less money for much more insurance coverage.
Both Progressive and Geicko have online, real-time quotes. very convenient and fast....plus, it allows you to change line-item details and see how it affects your cost. Interestingly, 50/100/50 coverage cost exactly the same as 300/500/300!
It's free, it's easy. I printed up my online quote for my car and truck and will be taking them to my nationwide agent tomorrow. "Beat their price or lose my business".
