You can read about the NÉOLIA Olive Oil soap eight-pack at this Best Things in Beauty link. There are two types in the package - Olive Oil & Shea Butter Soap and Olive Oil Soap - both appeal to me.
I know that not all Costco stores have the same stock, but if you have been looking for this, make the trip. It's worth it!
Buy the soap. Don't bother with the hair products. I hated them and gave them away.
