Do you price soaps differently if they have expensive scents? Some FOs (buying by the pound) are about $1 per oz. But some are as high as $4 oz. So if you made a 1 lb batch (4 bars) scented generously (1 oz of F), one bar has .25 of FO and the other has $1 of FO. That's a pretty big jump. Do you just assume it will all "come out in the wash"? I thought a solution MIGHT be to have the bars be the same price, but the ones with the pricier FO be a bit smaller, like 3.5 oz vs 4 oz.
