Many insurance companies offer extra perks such as discounts on outside services. For example, Liberty Mutual offers their customers Liberty Rewards. Some of their rewards include free issues to certain magazines along with discounts on obtaining your credit report and vehicle history report.
Now, the outside discounts that an insurance company offers is not a reason for you to switch insurance companies. However, to get the most out of your insurance premium, you should ask your insurance company if they offer any outside discounts from other companies.
Perks are nice to have, but the most important thing for me is that my insurance company is financially sound, especially in troubled times.
