Generally speaking agents don't know sh*t about insurance.
Generally speaking, Justin's right. An agent can say anything, but you're always at the mercy of the underwriter!!
A little tip when buying insurance that can save you alot of money is to have a copy of your "Loss Runs" from companies that have previously insured you. A new carrier wants to know if you've had any claims against you and Loss Runs tell the tale.
If you ask your present company for a copy of your Loss Runs it's a signal to them that you're shopping around, but that's too bad. It's a simple formality for companies to provide you with this very valuable information!!!
