Also, FWIW: Midwesterners who have trouble tracking down Gentian violet might try Hy-Vee. For ages I couldn't find the stuff to save my life, and then one day, as if by magic, it appeared out on the regular shelves of my local Hy-Vee's pharmacy department. IIRC it was ~$5-6 (though possibly cheaper) for 2 oz of 2% solution, Humco brand.
Mods, I apologize for the lack of tags. I tried to open the Select Tags thingy and it just hung, no luck.
