Apparently insurance ads that say the following work: "Those who've switched saved an average of $417!"
Although I don't know why. I dare you to get a quote from anyone else right now and see how much you'll save. It won't be much if anything.
Maybe it's like saying you could win a million dollars at the lottery. People have an understanding they're unlikely winners so aren't too disappointed when they don't hit the big one.
