Best Cost Car Insurance

Car rental Insurance coverage, Visa, Amex, Discover or Master Card--which is the best choice of the 4 options?

Does anyone know in general which credit card program offers the best CDW/LDW waiver option for a 2 week USA car rental? I have no car thus no insurance myself, but I have all four credit cards, Visa, MasterCard, Discover and Amex.

1. Why not just add the liability insurance option with the car rental agency? Thats what I did. Basic liability is all you need in most states and if you read the fine print, if it's not your fault the rental agency already has you covered.
2. Check with your company, most platinum cards cover you for the Collision damage waiver, but not the full insurance. If you don't have a car or car insurance, it would be advisable to buy the full coverage to protect yourself just in case there is an accident whether it is your fault or not.
