Identity Theft.

Back when I was going thru my divorce, I had one credit card with a $5000 limit that was always near the limit, due to the financial raping I was being put thru by the Dragon Lady. I bought something online, and the card was compromised, and they tried to buy something that was like $35, but there was no room on the card, and they tried to put it thru like 6 times in a half hour. The credit union with whom I have the card called me the next day and asked if that was me, and I said no, they killed the card and issued me a new one.

I have another card with a much higher limit and the company that issued the card called me one night and asked me if I tried to buy a $6000 car with the card, I said no, they also killed the card and issued me another.

I have only one card I use online now, and it's limit is really low, so if it does get compromised, there won't be much taken.
