Query: You can't be sure what you're getting

I ordered the samples of this product because I was interested in trying the sulphate free shampoo, which is expensive. The samples are REALLY random, so you may not get ones you actually wanted to try. Most of the ones I got were things I wasn't interested in. And I didn't get the shampoo sample. They say you can return it for a refund, less shipping and handling, but the shipping and handling were double the cost of the product itself.
