Recently, I stumbled across a neighbor having a moving sale who had tons of Erno Lazslo Dead Sea Black Mud soap for sale for a $1 a piece. I recognized the brand but didn't now anything about the product so bought a few bars anyway and WOW. I wish I had bought everything she had. After doing a little research that stuff is EXPENSIVE! $27 per bar for the small travel size but what compelled me to look into it is, this stuff really helped my skin. I have terrible cystic acne and it's cleared up. I haven't changed anything other than using this soap. So, when I went on line to see where I could purchase more, I was disappointed at its price point. I'm hoping someone can suggest other Dead See Black Mud Soap that is just as good but not as pricey? I'm guessing Erno Laszlo hike's up the price because of the brand name...
Try seacret of the dead sea. They have lots of different products. I think the bars you're referring to may be $12/bar. Check on ebay, you will get this item and other items alike super cheap! Good luck!
