Here is a great way to save 'stuff' that you buy online (or anything you want to save in a paperless manner.) Go to 'cutepdf.com' and download the apps, once you have installed the program and the driver you can 'print' anything you see online to a file that can be saved (and backed up.) This free program makes .PDF files out of anything that can be printed - I save everything that I get online using this program and it works great.
