Well, it is a supposition, but having checked how Sri acts with his marketing for the last 3 or more years, it is clear that he only made an unscented soap in the Donkey Milk base so far, the Bare Naked.
He didn't bother to make one as well in the Bufala base, simply because he didn't want to sell it in lower prices and thought that he could drive people to buy his recent, more expensive base, even though many of us prefer the unscented version for cost and skin sensitivity reasons. . He only made 4-5 soaps in his current base ALL scented, and that's it. (27$ all of them, without the shipping.)
How low do you think, will be the price of the Siero Unscented having already an experience with the Bare Naked that cost 20$? 20$ again? 19$? I don't expect it. You don't expect it either and you know it. It is just a guess, yes, and really sorry for the "fake news", but we all know how an artisan behaves when it comes to marketing. Again, I apologize for the supposition.
