This just in from my friend who left my house two days ago:
When I got home I got a call from American Express wanting to know if I had just tried to charge $600 which I had not. Turns out someone had charged over $4,000 on my card that day to some online dealer and tried to charge another $600 to a cellphone company. Amex took the charges off my account, cancelled the card and they're sending me another one. I had used that card at a restaurant or two and at the grocery store in Negril. Be careful.
