Have you tried going to www.drclarkstore.com. Their stuff is Syncrometer tested so you should not have any problems with getting something that is moldy or toxic. If you buy something similar in the local heath food store you may not know what you are getting. It may cost less but you may not be getting the quality you need. I have purchased from them and they ship the products rather quickly. They have a special discount of 3% to 6% off on products depending on what you order. I believe this to be the first store started by Dr. Clark.
