I purchased the bundle special offer for $8, and all of the products are great. I especially like the bar conditioner, lip balm, and deodorant. The bar shampoo contains sodium lauryl sulfoacetate, which makes sense because it foams up way more than other naturally-derived bar shampoo. It is similar to a Lush bar. The bars on the site now have different ingredients listed with no SLSA, so maybe the formula has changed. Regardless, SLSA is still less harsh than SLS, and this might be a pro if you have hard water or struggle with waxiness with other shampoo bars.
