I buy Kodak SM C-41 chemicals from Photo Finishers Supplies, Inc. I get a case each of Developer #KOC1756337, Bleach #KOC8824690, Fixer #KOC8462681, and Final Rinse #KOC1925254. No starter is needed and instruction for use can be found from Kodak on tech sheet CIS-211. I paid $250 for a case of each including shipping. This has processed hundreds of rolls and sheets in a Jobo processor. It is easy to get and easy to use. It has saved me hundreds of dollars versus having a lab process this film.
