Sorry about that. I had not looked at their site for quite a while since I have still so much. The smallest Flexicolor developer they have is 4X5 gal or 20 US gallons for over USD100. You live in NYC: doesn't B&H sell 5 liter sizes, even if they have to order it.? You could easily pick it up.
Seriously, this is getting difficult and the 'writing is on the wall' about future availability. None of us know what is going to happen, but B&H, I think, still has listed on their website small sizes of C41 chemicals. - David Lyga
I wonder about the logic. 20 years ago, there was a lab on every street corner, so the market for 4x5Gallon kits, was huge, now there are maybe 10 major labs and a few dozen smaller ones, so the market for those large quantity packages has got to be tiny, certainly a lot smaller then say the market for a 5x1L kit would be.
