Here's a site that sells the Mitui Gold for $.77 each for 100 to 500 w/o jewel cases: http://www.cddimensions.com/cd-r_media/mtc-r74tgg-cb.asp
and another where one can buy packs of 25 with jewel cases at $1.35 each:

Let your search engine do the walking.
BTW, black cd blanks by Memorex and PNY are said by some to sound the best for audio. Have tried them and they work fine, although I can't say I can hear any difference compared with others I've used. Look sexy though with gold lettering on a black background. <:)
