I actually get mine through my Acupuncture doc - she told me that she can get a much better price than I would be able to, so I just got it from her.
After doing a little checking I came up with two other sources with believable prices -
www.dudadiesel.com/search.php?query=sulfur&affiliate_pro_tracking_id=17:31:US and
www.nextag.com/where-to-buy-sulphur-powder/stores-html.
I receive absolutely nothing from either of these sites! So I'm only posting these because I wanted to help a little!!
Remember, it only takes a small amount for each application, as you only need to apply it around your ankles, knees, hips & groin, and around your arm pits. It will wash off as you sweat, like everything else does, but at least I'm not using
more chemicals trying to avoid being bitten again by tick, mosquitoes, and those lovely (HA!) chiggers!!
Best of luck to you!!
