Have you ever negotiated your car or home insurance premiums?

Is it possible to even do this? (e.g. same coverage/same company/same everything, lower premium). I thought that premiums were determined by actuarial formulas so the only way you could lower your rate was via some change to your coverage (e.g. changing your deductible) so I don't know if they can change the premium because you threaten to change insurers.

I was thinking of trying to see if State Farm would look for more discounts for me but I feel kind of dumb asking for a "discount double check". I might email my agent to ask.
