Here's some advice. If you mail order/internet shop often,use one dedicated credit card for purchases. Sure enough someone obtained our card number and made a fraudulant charge. The fraud dept caught it and cancled card and issued us a new one!!!!Later on while vacationing at Rehobeth beach,we learned from the hotel clerk that someone either hacked or though a security problem obtained amazon.com customer info. Never confirmed if this was true w/amazon. If it is true,it would have been nice to have been nofified by amazon.com. That is why we only use a low credit limit card for internet.
