I have most of the KBCO Studio C cd's available for sale. Almost all are in Like New or Brand New condition. $45. for #3 but most of the other ones will be $12 except for the double CD's (#20 and #30) which are $30 each. Discount for buying multiple discs. Let me know which ones you'd like and I can let you know if it's a new copy or a used one. Texting is the best way to reach me: (3 zero 3) 8- zero 7- zero 788. Cash or Venmo only. Thanks for looking.
