Yeah, I figured it must be pretty wide spread.
I think that even if there haven't been any unauthorized charges on your card yet, I'd consider canceling that one and getting a new number issued. I seriously doubt that if they were able to get any of the credit card info, they'd stop before they had them all. And while I'm not saying that I'm positive that the numbers came from HD Tracks, it's highly probable that they did.
But, on another note,..
I'll be there with bells on Romo!
