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
