Yeah I second that, I do not trust my CC info in anyone's database, I prefer the online stores that let you enter the CC info at time of purchase where it is then discarded and not stored in a DB on their systems.
Working in IT security I know there is no such thing as a 100% secure system.
Although I suppose somewhere this is info is online, say at the bank itself, but you can only do so much :)
I can't help but be amused when all these Luddites who steadfastly refuse to use their credit cards for online purchases routinely hand their credit cards over to clerks in stores and waitresses in restaurants. That is far more dangerous!
