We use to buy Iodine drug stores, to put in our baby oil. Even when I was in college we'd go to drug store for the Iodine to mix with baby oil~
Recently, 2 weeks ago, I bought 500mL of Strong Lugols at Costco for $23!!! Full strength...if you have Costco near you go ask. The Costco store here in VA did say to me that it was their last bottle.
I may go to another town and drop in on Costco and see if I can score another bottle!
