I asked the Formulary and they said they couldn't help me. (I did just place an order with them for a bunch of other stuff, though.) I'll check with Kyantec if Science Lab falls through, and maybe check again with the Formulary. Perhaps they'd order from one of the sources I've identified and then ship it back out to me if they don't have to track it down themselves....

Also FWIW, at least one of the pages I found on this developer specifies that CD-1 should be refrigerated for storage. I'm reluctant to put the stuff in my one fridge, which I use for food, so I'll just try to use the CD-1 (and therefore the film that requires it) quickly instead.
