Where do you get such cheap KI to make a quart of SSKI ? Or did you mean it costs you $20 to make a quart of Lugol's?
I think it would take about $180 worth of KI to make 32oz of SSKI at $20 for 100gms of KI crystals. It takes about 100gms KI to make 100ml of SSKI so it would take roughly 900gms to make 32oz of SSKI. Rough estimates only.
Who is your source of KI and are they a reputable source? I'm paying about $24 for 100gms now.
