I have some CPAC darkroom chemicals I purchased from a local
school when it closed down its darkroom. From talking to the
photo teacher, the chemicals are the last batch and they have
had steady shipment flow. He can't specify the exact purchase
dates. He would speculate that they are about 1 year old.  This
is what I have:  Item Product Code List Price C-41/TL-50 Film
Developer Starter (bottle) 55DE519 $4 TL-50 Developer
Replenisher Kit 55DE571 $95 Trelux-23 Bleach Replenisher 55BL543
$160 Trelux C-41 Film Fixer Replenisher 55FX557 $33  ColorPAC RA
Processing Kits 35RA350 $70 TriPhase RA Developer Replenisher
(bottle) Universal RA Bleach-Fixer 30BF395 $73 ColorPAC RA
Bleach-Fixer (bottle)  The only items I do not have are the film
stablizer and RA developer starter. The last are the CPAC
marketing prices.  These chemicals are particularly good for
small photo lab and pro photographers who have some steady flow
in the darkroom. They can also be used by home user. Most of the
bottles make either 5 liter or 10
