Movers Insurance - a good idea?

[volcs0]

Our movers have "included" insurance, which is basically covers us for about $8000, say, if the truck were to blow up.

For $600, they offer $75,000 protection.

My questions:

1. Does my home-owners cover anything?
2. I'm paying for the move with my Amex. Does that cover anything (I have not called them yet, but will).

I'm not really a risk taker, but $600 on top of a $9000 move sounds like a lot of money.

Thanks for the advice.
