(navarone: "Finally! Povidone-iodine extraction!", Stimulants) As you can see the process for extraction of povidone deals with sublimation in order to get pure product. Povidone Iodine is more trouble than it is worth, the $2.00/oz is most likely the best bet, for now. Keep looking, there are better sources.
When shopping in these feed stores sometimes as you noted in your experience the clerks will try to offer a substitue, don't let them make you buy another product, assert yourself. On the other hand, if one gets a particurly bad vibe, then sometimes it is best to shop another time and or place.
