Many people pick an insurance company and then stay with them for many years, myself included. When I first started driving, I stayed with the provider my parents used. I stayed with them for over 15 years. Then I read about people saving money by switching, so I decided to look around. I ended up saving close to $300 per year on my coverage. Recently, I switched again and saved another $100 per year.
It may seem like a hassle, but simply taking 15-20 minutes to get a quote can save you hundreds of dollars. There is no guarantee of course, but at least you will know that you are being charged a competitive price. Plus it free! Below are a few insurance companies that I recommend.
