Hey mrclunk,
What is your intention? You can use the recovery system or download the installer from the app store if your machine is approved for it (bootable usb drive: http://lifehacker.com/how-to-create-an-os-x-mavericks-usb-installation-drive-1450280026). If you did download already, then it will show up in your purchases tab where you can then re-download it. Third option (if you use a not approved mac) is to try the Mavericks download enabler: http://forums.macrumors.com/showpost.php?p=18361110&postcount=677
Sending a copy is not that easy, as the file is very large.
best regards
