I highly suggest all you of take advantage of the online features that your credit card company offers, it helps you keep track of how much money you spend and so on. However, ENSURE that your computer is virus free and is secure.
If you get a lot of pop ups or weird programs that you didn't install, then your computer may not be safe. I highly recommend installing a firewall and anti-virus. There's free ones out there, such as Free AVG and Zone Alarm Free Edition.
