I had Farmers(?) Insurance.
I've got Farmer's for my personal and business Workers Comp/Liablity. Great rates and when I had to file a small claim, great service. Use to have State Farm. YMMV
I saved $2,700 from Farmers (which I had before) -- and I found it on Mercury.com that actually computed that The Hartford would be cheapest.
It sort of restored my faith in Humanity.
"GEICO'S rates are so "unfair" I saved $3500 on my auto insurance. "
What? I live in Yokohama, and have been paying around $700 a year.
Hate to tell you this but my entire annual Geico premium for three vehicles is just under $700. I did get a quote from AARP (DIDN'T join), and it is $100 cheaper yet.
I just saved $1,200 and also had Farmers.
