That's what I was told when Vanbar
called me back to discuss an order. I'd ordered some cheap (AUD$2.50/roll) Lucky brand film (on the "how bad can it be?" theory) and some HC-110. They called me back to say they were all out of cheap film (of course) but could ship the developer if I still wanted it, which I did.
The guy who called me, however, noted that Kodak had discontinued distribution of HC-110 in Australia and that my order was for the very last of their stock.
None left. At all. Never to be replaced.
If this is so (I couldn't find anyone at Kodak who could tell me a thing about it, although I didn't try that
hard in ringing around) then it is probably all my fault, as I decided to use HC-110
in a personal project. Of course a material I decide to standardise on wil always be immediately discontinued. That is in the nature of things.
So everybody should start really worrying about the availability of Tri-X
