Thanks for the heads up, as I will look closely at my charges, when I get my Target bill. I'll aslo have to check to see if I can view my staement online, to be proactive.
My CC, (not Target), had a charge for $99 on it and my CC company cancelled my card immediately. They were on top of it. Unbeknownst to me, I thought it funny, when I swiped my card shortly after they cancelled it, at Publix and it didn't work. My first thought was their machine was having problems or the magnetic swipe was defective. I found out the next day when I called them.
There seems to be alot of CC fraud going around these days. I think one should be circumspect, especially at the gas pumps as I think that was how my info was comprimized. Fortunately, the CC company waived the $99 charge and issued me a new card. Great work by them but inconvienient for me, as I have only one CC. they sent the new one via fed-Ex so i had the next business day at their cost.
Hopefully, they will do the same for you and you won't have to carry a lot of cash with you.
