Yep my CC was hacked as well.  Over $1300 was attempted to be charged at Walmart.com.  Luckily my CC Company realized what was going on and declined the transaction, and then notified me immediately asking if I was the person placing the transaction.  I told them I was not, and they have cancelled the card and are sending me a new one.  Though I guess I'm glad it was only the one transaction, which didn't go through.  All of this happened last week, and now today I receive the notice.  At least now I know what and how it happened, but I'm still disappointed.  I'm going to spend some time weighing whether or not to continue to do business with Renderosity, which is too bad since the vendors here are top notch.  If I do decide to continue I will only use Paypal going forward.
