Just a couple of months ago my credit card would not work at the grocery store. By the time I got home, I got a call from the cc company saying someone in Destin, FL was buying 800 worth of stuff at Wally World. I said, thanks for letting me know since I haven't been to the beach in a while. They cancelled the card and sent me a new one right away.
It is so easy for anyone to get your information. Stores, online, mail, etc..
