Just grabbed some cheap memory from mymemory.co.uk, might be worth a looksie. Have a Google to find out what memory it takes
Most retaillers sell the various adaptors [some multicard] to have the card plug into your PC without using the software. I have found though that it's sometimes easier to let them use the software rather then show them how to deal with dragging, dropping and making folders etc.
One consdieration is that unless the camera charges via USB then using the standard lead to transfer the images will drain the cameras battery.
