It looks like Costco is a pretty good deal. Shipping with BA is up there.I think that's what's on the label with the Fx CO I the first time I bought it from a soap supplier. (Not the organic part.) And Bulk Apothecary sells it as such as well. I don't recall where I first bought it, but I was really surprised by the label and it caused me some confusion at first.
Here it is at BA.
