Interesting post, thanks. First, I do not live in the USA so would have to pay expensive shipping and import costs from there. However a friend did bring some over. Taking the blackberry as an example: BB's blackberry cybilla: 16 oz = 454g and the cost is $17.12 plus shipping, add say $1.88 for shipping. I use 100g per 2Kg batch, so at $19 per 454g = $4.18 for the fragrance. Using my recipe and converting from peso to dollars, I get: 100g avocado oil, $0.83 500g coconut oil, $1.71 600g shortening, $1.79 250g soybean, $0.60 250g sunflower, $0.75 NaOH 1/4Kg $0.50 Total . . . . . . . $6.18 $6.18 for all ingredients except for the fragrance, then add $4.18 for the fragrance?! It represents 40% of the cost of the soap And even ordering 5 pounds from BB reduces the cost only 10% which is clearly not enough. But if I source 'red berries' instead, the soap smells actually slightly nicer, and my cost is now $2 for the fragrance, representing 23% of the total cost
