Don't forget to read the fine print. A lot of coverages leave out the small stuff that really can add-up like rental car coverage, car rental while yours is getting fixed, glass coverage, etc.
Sometimes that $10 you 'save' comes back to bite you in the a$$.
Call me old-fashioned, but I also like having a agent you can call, text, or email at pretty much anytime. I have been with AmFam for almost 15 years, and my agent is worth his weight in gold. He will do ANYTHING to help you out and be your representative. Even if I found cheaper rates, I lose the personalized service. It's hard to put a price on excellent support.
