Pretty much the same story here but different companies.
We were with Safeco (owned by Liberty Mutual) for years, with only very slight increases in premiums. We had 2 Autos, Home, and a $1M Umbrella policy.
Last year all premiums jumped by a lot, maybe 30-40%.
I started calling and asking around, ended up with a broker who recommended Erie Insurance.
We were able to add coverage, increase our coverage, and double the Umbrella, and ended up with premiums that were HALF the renewal cost of our old company.
I'm now paying $537/year for the 2014 Ram, $1081/year total for both cars. Safeco wanted just over $2000/year.
None of these details should matter to you, there are too many variables, but the idea is to show what you might gain when you shop around for insurance, for example by reading experiences at
