-I'm not picky with what brand name disc's are used. -DAO, disc at once, is a must!! I hate gaps & clicks between tracks! -I enjoy larger trades, 20-30 disc's or more... It seems to me a waste of shipping money if the trade is less than 20 or so since disc's way nothing. -No writing on the disc's please! Let me label my disc's the way i choose. I will not write on yours! -I use bubble mailers & of course sleeve when shipping, if neccesary i will use a box, but wil not allow space for movement inside. Newspaper or scrap paper of any kind work fine as a filler. -Check out MY WEBSITE & CD COVERS@www.organicgroovecds.homestead.com
