I make my own lavender or lemon scented. Don't remember the base cost for all the ingredients (olive oil, coconut oil, canola oil, lye, water, scent... that's it) but I charge $1/ounce after at least 4 weeks curing. Next time I buy ingredients I'll have to work out the cost per bar again. I use my soap for bathing and dishes and sometimes make up laundry soap too.
Remember, he's not a tame lion.
