Good Sam Insurance Offer not as presented?

I think that's a good practice.... when they (any insurance company) asks what you are currently paying, don't tell them. Let them give you their figures first! If insurance A can save you X # of $$$ and you switch, Then insurance B can save you X # of $$$, eventually, you should be able to switch insurances enough, you should be insured for free! (But it don't work that way now, does it?)
