@SarahGen-- Although a bar of all natural milk soap isn't the most affordable, most brands have very large bars. So a single bar lasts quite a while. And how quickly a bar of soap dissolves actually says a lot about the quality of the soap. A good quality soap should last for a while. So in that sense, I still feel that this soap is worth the cost.
Also, I highly recommend checking online stores for milk soap. I bought a pack of lavender scented goat's milk soap recently online. It was a great deal, I saved a lot of money. And the soap is a great quality, a European brand. So you can definitely find affordable milk soap if you look out for it. And this particular soap is particularly soothing and relaxing because of the lavender scent.
