That's how it starts. - Phil Boiarski

No - amazed they even caught it! - Mona Nomura from fftogo

Yes, definitely close it. It has been documented that fraudsters make one small charge (hoping to remain unnoticed) to validate credit card numbers. And your credit card company already brought this to your attention and you said no; I don't know how this impacts liability (by law, you're only liable for at most $50 of unauthorized charges). - Tudor Bosman

I would. - Alex Scoble

Same here. - Chris Baskind

The good news is we figured it out. No fraud! But it was interesting that just about everyone said to cancel. More later. (I'll blog it) - Louis Gray

i closed mine on a 1 dollar charge 2 weeks ago - Steve C

Having been in a similar position before (Didn't get a call from fraud about it, but I noticed an unrecognized charge, didn't report it because I didn't want to get a new card), small charges like that are just to test out the card to see if it'll work, followed by several small charges that'll generally go unrecognized or a big kahuna charge while the card's still usable. It's an inconvenience to get a new card, but it's weighed against the larger inconvenience of being wiped out (at least partially and temporarily) in the event of a fraud. - Mark Trapp

Yeah, I wouldn't close it until and unless they told me when and where the charge was made. - Ken Sheppardson

I remember reading about the relative value of a CC on the black market .... oh, yes - here it is: http://www.slate.com/id... - Micah Wittman
