I still get raw chemical components from Vanbar.
I also get minilab chemicals.
On tuesday I'm getting a whole massive amount of Flexicolor and Ektacolor Kodak Chemicals too for shipping cost since it was going to be tossed and offered to me.
AFAIK I tried to get thiosulphate from Vanbar and they dont sell it any longer but have it listed still, I'll inqurie again, they have useful stuff like potassium hydroxide for making potassium salts, carbonate, benzotriazole, hydroquinone, thiocyanate.
They also sell Kodak E6 minilab 20L kits of Fixer, for like $15, if you want fixer look or that, or get universal fixer.
Hypo is just metabisulphite or sulphite in water (usually the latter, sometimes both).
You can get Sodium and Potassium Metabisulphite really cheap at Vanbar, and many super markets stock sodium metabisulphite (sold as steriliser) in the home brew section, sodium sulphite I found at a pool shop that sells pool chemicals. If I can find that in a pool shop in Byron along with other useful chems, I'm sure you can down there in the city
If you cant get thiosulphate, and want it for something other than a fixer (so cheap thiosulphate fixer is no go) then you can heat sodium sulphite + sulphur in water to make it. It's probably as cheap as buying it, you can get Sulphur on ebay for about $20/kg, and $15/1.5kg for sulphite from a pool shop.
It should be rather a simple process actually, I'm pretty sure its just 1 mol + 1 mol = 1 mol of sodium thiosulphate.
32.065g of sulfur + 126.043g of sodium sulphite dissolved in water and heated should equal 158.108g of sodium thiosulphate, unless I'm missing something.
Sulfur wont dissolve, but should react in the heated presence of sulphite dissolved to form thiosulphate afaik.
