Hi, I internet mail order most of my stuff from vanbar, they have basically every chemical you could want at great prices (for anything sold in Australia that is), anyway they dont appear to have CD3 or CD4.
If anyone has a clue where to get some please spill!
Getting stuff from the U.S. nomally starts at bout US $40 shipping (not the actual shipping cost, but thats what shops like to charge! even for a single roll of film, lol).
Actually, I believe most of the modern photo chemistry sold as individual constituents comes out of India these days.
I have bought cd-3 from Artcraft, and to save on the effect of postage I ordered a pound ie 450g. I have not uesed much, but it is happy in a glass jar in my freezer. My cd-4 came from jd photochem
