I bought the products from iherb.com. I've purchased my supplements from them for years. They are very fast, and respond quickly to fix the very rare problem.
I chose the Frontier Co-op, Organic Mullein Leaf, Cut & Sifted, 16 oz for the tea (a very large amount!) and Nature's Answer, Mullein Leaf, Fluid Extract, Alcohol-Free, 2,000 mg, 1 fl oz. Hope it works for you!
