May have a look at the Kodak wetting wet then ....

How much is b/w film, I import from the USA. $6US a roll? 6+76 = 82/6rolls = $13US.
I'm sure the Ilford Ilfotol will also be very long lived. It is just a concentrated surfactant, so oxidation isn't an issue.
Just for clarity, you only mix up what you need each time, leaving the rest of the concentrate in its original container.
Using Ilford's data sheets, 100ml of stock ID-11 has the capacity to develop one film, so if you dilute ID-11 stock 1 + 2 one litre of stock will develop 10 rolls.
The Kodak regular (non-hardening) fixer is available in powder - Ilford doesn't make a powder fixer. The Kodak fixer will fix 26 films for each litre of working strength solution.
Yep, aware of the storage lifes as by the manufacturer.
The liquid developer like the ID-XX can sit for 24 months in full bottles. It however cost $50US equiv here for the 1L conc size. It quotes 13 rolls of film (1+4), it doesn't quote any for a higher dilution. This is $3US/roll. Compared to ID11 which is $1.45US/roll again sticking to its suggested 16 rolls for that 1L mixed up stock solution (1+1).
Seems to me that powder is the way to go. I can mix up the entire packet for each 6 months, people say you shouldn't mix partial packets of powder.
The Ilford fixer is liquid. That last 6 months according to them, longer if I test it etc ... Again with the powder, it has to be mixed up a stock anyway....
Kodak doesn't provide these datasheets like Ilford online. I have tried to look at their website and the Tech Pubs.
The Ilford washing aid is - 3yrs in its conc form liquid in full bottles. When it is mixed to a 1+200 solution the life is just 7 days. Yeah .. the 1L size Ilford provides does 666 rolls of film, yes for 3yrs but that is heaps, I certainly won't even use 1/6 of that over the 3yrs. Prob less than 1/12.
The following you don't have to worry about for years:
Stop bath or any other basic acids.
Photo flo unmixed or equivalent.
The rest will either oxidize or sulfur out eventually (fixer). My suggestion is to shoot more film but 20 rolls should be fine for 5L of chemicals over a year.
Ilfotol is available in 250ml and the equivalent from other manufacturers comes in even smaller pack sizes. You mentioned that it is a "washing aid" - no it is not. The Ilford washing-aid (used to remove fixer by-products from fibre-based paper) is called "Washaid" and is not required for film. Ilfotol is a wetting-agent, to be used in the last rinse of the negs before drying them, and is not required for paper.
If you want to use ID11, then remember to dilute the stock solution immediately before use, not at the time of mixing. If you buy/mix a film developer in a one litre packing (liquid devs are also available in much smaller pack sizes) then split it into smaller bottles with no air and use them in turn. If you wanted a more economical Ilford liquid developer then look at Ilfotec-HC, which can be thought of as the Ilford equivalent of Kodak HC110. If economy is very important then you can use D-76 in place of ID11 and it is half the price, or less. Liquid developers are also available from other manufacturers at half the price of DDX.
Is the reason for using Ilford products (apart from the excellent quality) local availability? It might be cheaper to order from Europe, USA or Japan?
Shopping is the first answer. You may not find just the thing you want in a small size, but you can probably, with enough work, find something suitable. Homebrew is the other answer. One of the reasons I bought a good scale and started mixing developers and fixers from scratch was that I didn't really do that much darkroom work. Putting things together from their ingredients allowed me to mix small batches right when I needed them. (The other reason for doing this was that I like to experiment.)
You can basically ignore the 3 years limit - it will only apply if you expose the Ilfotol to the most harsh of circumstances. Surfactants are generally quite robust. Developers are a bit different.

Most of the most valuable ones are found through this link: http://www.kodak.com/global/en/profe...ankIndex.jhtml
The most useful one for your purposes is probably this one: http://www.kodak.com/global/en/profe...3cf/e103cf.pdf
That table is found under the "Chemicals" sub-link on the first page I linked to.
If you want a powder developer that will develop 60 rolls of film from a single package, buy a 5 litre package of Kodak X-Tol, mix it up and split the five litres into five 1 litre bottles.
Use one of the bottles as your working solution, and the other 4 litres in a simple replenishment regime (70 ml per film).
It should last longer than the projected 6 months, but even if you decide to toss what remains after 6 months, it will still work out to be very economical.
I would suggest, however, that you include two packages in your initial order - you will save on shipping.
I don't think shipping is an option. Maybe eBay from Asia?
B&H basically charge a min order of $40US for delivery. Ie one roll of film. Freestyle has been my choice, their films are a bit more but cheaper freight. However a single bottle of 500ml rapid fixer liqiuid cost $20US for freight. If it was 2x 500ml bottles the freight becomes $30US.
I go to Asia somewhat annually so I could pick it up there but not sure if they are as cheap or what ....
I want to keep the quantities down. I don't shoot enough. So I prefer a 1L made up (undiluted) using a powder developer than a 1L of liquid. The powder ones here seems to be cheaper per roll or film. Even if I did the suggested 6 rolls for the ID11 (powder). Compared to say 16 rolls of IDXX. Yes there is LC29 but I just won't use enough of it, it suggest I could do between 16 rolls to 50 rolls by diluting it more and it last 36 months in full bottles according to them (unmixed concentrate), much of it would be thrown out...
I think the ID11 or similar would be the way. 6 or 13 rolls for the 6 months. This is a first timer so I prefer something easier to work with too...
250ml of Ilfotol? I did my search at the mailorder giant B&H, thanks. I was basing it on them, they only did 1L.
Just use powders then. There's very little difference, they weigh less, last way longer, and are easy to mix. I'm in the US and I use powder developers.
On top of that, you don't *need* a rapid fixer for the volumes you're doing - a standard sodium thiosulfate fixer will work just fine and this is easily purchasable as a powder. Mixing is brain-dead easy. The only reason that rapid fixers are liquid is because ammonium thiosulfate is not stable as a powder.
Stop bath? White unscented vinegar. Photoflo? That you should buy in liquid form but a single 500ml bottle of PF will last you literally *years*.
Photographers Formulary and a scale is most cheap. No penalty for mixing a liter.
D76 or ID11 has a 6 month life after which it dies slowly. 50% full bottles are good for a day, no more. After that activity goes up rapidly, then dies fast. It is not predictable. I have done tests, very careful accurate tests.
Rapid fixers are good for 6 months, after which they sulfate out. You need this type for TMax and Delta films. For others you need plain old powder sodium thiosulphate types from powder or Rapid types also work.
For home developing you must decant what you make into small one time use bottles.
Beware of Sodium asbsorbate developers that do not turn brown as they go bad, Xtol, and the liquid Ilford developers. Actually you do not not how old they are when you buy them and depend on stores stock rotation. Bad developers=low contrast.
Do not even think of breaking down a gallon bag to make smaller ones. #1 the chem are not necessarily mixed !00% and #2, they are packaged in a nitrogen atmosphere to retard oxidation.
