Sounds like usb is what your camera takes. Just take your camera with you to make sure you are getting the correct size/connector end. With that cable (which you can generally buy for about the same price you would spend on a disposable camera & film development) you should be able to transfer pictures through a direct connection to your computer and eliminate the retailers all together. Firewire is a highspeed data transfer cable, and USB2 is a little bit faster than Firewire.
