Good shampoo for the price
Style: Shampoo
I like the scent, it's very subtle. It also cleans my hair well. It's not a top of the line shampoo by any means, but it's good for the price point!

Well Worth the Price to Stock up on!!
This is my favorite dish soap. It foams and cleans as good as if not better than some brand name foaming dish soaps that are out there. It's difficult to find in a brick and mortar store, if you can. When I found them here I bought them right up.
