I'm looking for non-photographic sources of sodium sulfite, as shipping overseas is prohibitively expensive. WHere would you look for this stuff in other sources? I've heard it's used as a food additive, for instance, what kind of store might carry it? I'm not in the States. so none of the usual sources for photo chems apply. Thanks.
Say where you are, then it would be easier to help.
Its usually Potassium or Sodium Metabisulphite that are used with food. Sometimes peeled potatoes or chips are stored in a weak solution, stops them going brown.
This was recently touched on. I get mine at a chemical supply house for much less than photo stores and it was advised that you can get it in swimming pool supply houses as well. I think it has several uses.
It should be very easy to find, ask a school where they get there lab supplies, it isn't expensive and is very common. It's definitely not worth posting from abroad.
Another option is ask your pharmacist/chemist shop (drugstore) often they can either buy for you or suggest where to try.
Fanshaw, I was used to buying chemicals in bulk, some like Borax by the metric tonne, others in 50kg bags. So I have contacs with a number of suppliers.
I generally use Scientific & Chemical Supplies in Darlaston for smaller quantities, but they supply school, colleges, universities and companies, not the public.

I think a tonne of borax would exceed my lifetime needs by several orders of magnitude!
50 Kg of sodium sulphite, though, would be worth considering if the price was right. I have contacted swimming pool chemical suppliers, but they don't appear to use sulphite in the UK.
