For now I'm giving them a 3. The selection is very good. In terms of service I've dealt with the following: a grumpy old asian guy, two helpful ladies (knew where the product was or would help me to get it from the back), and then there's this other hippie kind of dude who is very helpful and has a lot of knowledge (and his knowledge wasn't always correct but out of the 100 things he told me at least 75 of them were right). I do wonder about their herb quality. For example I took some oat straw and brewed it at home and it made me feel incredibly wierd in a bad way (heavy metals??). In this day and age though it's a bargain buying mostly any supplements or herbs since there aren't a lot of regulations. I'm also not sure if there product is impure but just going by anecdote here. If I were rich I'd test their products for impurities. I am going to ask them about where their products are grown, if it's possible to visit the facilities and what kinds of quality control measures are put in place. (fact of the matter is, many of the herbs will uptake metals or be contaminated from the environment unless under strict control or good environment)
