Buying Kodak Flexicolor chemicals for C41 processing is just plain difficult. It's hard to figure out what you need in the first place because there are multiple flavors (LORR, SM, RA, and regular, it seems). No supplier stocks all of the CAT numbers, or even necessarily stocks compatible quantities of the various chemicals. Kodak keeps changing the concentrate volumes and CAT numbers. Some are in gallons, some in liters. Vendors sell different minimum or case quantities. The prices are all over the map. The sticky List of Color Chemicals and Where To Get Them at the top of this forum is not even especially accurate or very useful anymore for Flexicolor C41 chemicals. I have screen shots of my shopping cart at Adorama, Pakor, and PSFNY down below to illustrate the point. I went looking for Ed's list of chemicals from that sticky thread: # 444-0296 - KODAK FLEXICOLOR C41 FIXER AND REPLENISHER, 5 GALLONS, 4 PER CASE, KODAK#1693837 $6.66 # 444-0364 - KODAK FLEXICOLOR C41 DEVELOPER REPLENISHER, 5 GALLONS, 1 PER CASE, KODAK#1919042 $23.10 # 444-0375 - KODAK FLEXICOLOR C41 DEVELOPER STARTER, MAKES 17.75 GALLONS, 1 PER BOX, KODAK#1953009 $4.50 # 444-0401 - KODAK FLEXICOLOR C41 BLEACH, 5 GALLONS, 1 PER BOX, KODAK#1987924 $77.21 # 444-1044 - KODAK FLEXICOLOR C41 FINAL RINSE AND REPLENISHER, 75 GALLONS, 2 PER CASE, KODAK#8486268 $34.00 Note in the above list, the 444-nnnn numbers are Pakor numbers. The Kodak CAT numbers are at the end next to the prices. Those prices are from 7/25/2011, and in several cases they are considerably higher today. Much of the price difference appears to be due to the replacement of the one part bleach with the two part Bleach III. I tried to match up the list above as best I could at Pakor, PSFNY, and Adorama. It's impossible to match it up completely. PSFNY does not sell the 5 gallon developer / replenisher CAT 1919042. Instead, they sell CAT 1532753, which is 5x5 gallons. Neither Adorama nor Pakor sell the 5x5. They only sell the 1x5 gallon. So to make it somewhat comparable, I added 5 of the 1919042 to my cart for Adorama and Pakor. At PSFNY and Pakor, you can buy everything you need for process C-41, although the costs are wildly different. At Adorama, you can't, because they don't sell all of the chemicals. I find it rather bizarre that Adorama sells part A of the bleach, but not part B. A huge difference you'll notice in the prices below between PSFNY and Pakor is the because of the Final Rinse and Replenisher. At Pakor, 12x12.5 gallon is $12.01. At PSFNY the exact same thing is $161.41. How weird is that? Now none of these have shipping calculated. I know from experience that Pakor will be outrageous, and they can't even tell you exactly what it will cost if you call them on the phone. You won't know until it is shipped. For what I have listed for Adorama, it'll be $103 shipping. PSFNY will be $144 shipping, but that is a considerably greater amount of product than from Adorama. Even with Pakor's typically high shipping cost, I very much doubt they could be more expensive than PSFNY, mainly because of the price difference for the final rinse. To get the best prices, I'll have to split my order between PSFNY and Pakor (that $12.01 for 12x12.5 gallons of final rinse is a steal). I wish I could just buy this stuff in a conveniently packaged 5 gallon kit.
