I'm sure many companies would bundle home and auto to give you a good discount. The funny part is with companies like Progressive is they make you pay a premium rate, and you get tier 3 service. When you do have a claim you get the worst quality repairs possible because they force a shop to use some junk part they found in a puddle in Ohio.
I have Erie ins. and my rate was over $100/6 months cheaper than the others with much better coverage. Some of the better companies also have packages you can purchase to use only OEM parts during repairs.
