I suggest that you contact Amex directly, and if they say you are covered for Priceline rentals charged to your Amex card, ask them to confirm that by letter or Email so that you have it in writing. By the way, why are you purchasing the premium car rental insurance? Doesn't your Amex card provide basic LDW coverage for free?
