How to switch?

I am debating switching car insurance companies. Since I got married, we have been with Farmer's because my sister-in-law is an agent. However, I am beginning to wonder if we could get a better price with another company. I guess the Gecko got to me.....

I am really worried about having to tell my sister-in-law that I am looking around, let alone that I am dropping her company for another one! She is very sweet and I can't stand the thought of hurting her feelings, but if it could save me money, Heaven knows I need that right now!
