First, check to see if you have the right amount of coverage. There is nothing to teach us about this, so when you buy car insurance, you probably don't know the coverage option to choose.
Second, find out what kind of coverage you currently have and how much you pay. Don't be lazy-do this. If you don't have your info in front of you, how can you expect to save? Either call your car insurance company or use their websites.
Third, it's time to start shopping around. I prefer the phone because I usually sweet-speaking rep to tell you about other offers that the site does not offer. The computer, however, seems immune to my charms.
I make it easy for you. Here are the phone numbers of a large insurance company:
Geico: 1-800-861-8380 / AAA: (866) 539-8033 / Allstate: 866 704 9900 / Progressive: 1-800-776-4737
Fourth, being an expert caller by asking these questions.
