I had a jewelry store card that was $0 balance hit before last Christmas to the tune of $7,000 (the limit). I strongly suspect it was an inside job, as the card wasn't a 'debit' or Visa/MC but just a store card. It was used in a store in Juliet, Illinois.
I have never been to Illinois (nor do I plan to ever be) so we reported the fraud as soon as we got a statement (with a $0 balance we didn't get any statements so when it showed up it was a red flag)
I guess someone in the Chicago area had a nice Christmas. They completely closed the account and cleared it for me, but it had already been reported to the credit bureaus as a maxed out credit card. Took a few weeks to clear all that up.
So if you have a store card with a zero balance, call and have them put a hold or pin on it, dont let that credit just sit out there waiting for someone to find and steal it.
Also, I use a gas station card to get gas, not a general debit or VISA/MC..........this limits where a thief can spend the ill-gotten gains from a card skimmer. Shell even offers a 'debit' card that only works in their store and has a 20-gallon per transaction limit.
