Credit Card Thieves

The holidays are here (duh!) and with it dishonest people.  This morning we got a call from American Express, seems like someone bought a Coach product to the tune of $500.00 and then another charge through Yahoo. I didn't know you could buy anything from Yahoo or through them, does that make me an idiot? I used the card last on Amazon.com and at the grocery story because we get airlines miles.  I wish these people worked half as hard at a real job as they do being dishonest and criminal.
