Once I can log into our AMEX account (it is currently closed/locked until we set up new card), I will post where we used the compromised card. I think we used it only 3 times. I believe we only used it for transportation as we like the extra insurance benefits AMEX offers.

Also we used another card (Visa) primarily for restaurant purchases which include some of the establishments mattt used his card. Our Visa was not compromised. I will post the list later on today so that it eliminates suspicion against the vendors mattt frequented.
