I bought some from Midwest Brewing Supplies to use in a braggot. It seems like some of the large brewing supply stores carry it, for reasonable prices (I think it was 2-3$ for two ounces).
I didn't use very much though--only 1 gram for a gallon batch...didn't want the mead to make me see things. Or poison anybody.
There is one secret ingredient that makes anything better......time.
