I just bought 50 dvd-r w/no spindle/no case for 1.24ea from <a href="http://www.cyberguys.com"> cyberguys</a>, and shipping was figured into the price per disk.
They also sell <a href="http://www.cyberguys.com/templates/SearchAll.asp?search=cd+cases&child=&curpage=2&ureq=y">these cases</a> which are great for fitting into your notebook case when you are flying somehwere.
EDIT, I was trying to point to the quad cases. They are small and very nice.
