Sodium Metabisulfite vs Sodium Sulfite
In Brazil we have all sorts of dificulties to buy raw chemicals. As a doctor I can buy some using my business (i own a private clinic) as an excuse, and I buy for some friends. The prices aren't so good but are affordable. I can't find some items like phenidone, glycin and chemicals for E6.
The prices here (converted to dollars): sodium sulfite $1.40 1kg, metol $50 100g, hidroquinone $30 500g, borax $10 1kg... much cheaper than buy d76 from kodak
