All,
We recently were informed by All-State that our yearly renewal was going to be significantly higher (50%) due to last years wind storm and increased claims in the area. We have never had a claim ourselves, and I quickly discovered this increase was not justified after some research with other insurance companies and the Ohio Dept of Insurance.
If you are faced with a similar situation, I strongly urge you to contact your agent and seek out quotes for comparison. I ended up canceling both my auto and home policies with All-State and transferred to State Farm in a matter of an hour and a phone call. This was extremely easy and hassle free, involved no money out of pocket, and gave me better rates than I had already (despite my thinking that I had great rates with All-State).
I went with Tito Paul on Winter Street in Delaware, I recommend him for a friendly, quick and easy transition. www.titopaul.com

So we took your advise and called State Farm and now we have more coverage and a lower payment. 
Thanks Nathan
