Bests & Worsts Reviews from Amazon

I first learned about the benefits of wheatgrass juice powder from Dr Berg and bought his product for about $40. But then later saw this other brand (Triquestra Health) that's almost 50% cheaper -- the same exact wheatgrass grown on volcanic soil in Utah -- it's just missing Dr Berg's lemon flavor. I'd like to support Dr Berg since he brought wheatgrass juice to my attention, but if this other brand can make a profit at $23/jar, Dr Berg is greatly overpricing his own product.
