Yes this saved me a lot of money; and I believe I have mentioned the site before, thanks to you Jonsher; hows life?
My "reason of purchase" is that I use it for photographic development / art. Kind of true.

Hello there,

New here, and just saw this link.
Thats a real good price.
I did have a place i was going to recommend but its far more expensive.
Im also from England.

The general rule here is to count the iodine; in Lugols 5 % = 6,5 mg in each drop.

lugols 5% is a solution of 5% elemental and 10% KI(potassium iodide). it is figured by the drop to be approximately 6.25mg of total iodine. that is 2.5mg of elemental and 5mg of KI. the Iodine content of 5mg of KI is 3.75mg. so Lugols is reckoned by total Iodine content: 2.5 + 3.75 = 6.25.

when i take 13 drops of SSKI it equals 390mg of KI. 97.5mg of that amount is potassium, so the total Iodine content of my 13 drops is 390 - 97.5 = 292.5mg of total iodine as is figured in lugols.

clear as mud, right?
