Amazon had the cheapest deal on this product at the time
I'd been using this product for a while to supplement my poor diet and found it on Amazon for a lower price than in stores.  The scoop in these containers is much larger than what I am used to and I added way too much on my first serving so pay attention there.  The product itself doesn't mix the greatest and can definitely be tasted but I've found that I like tomato juice even better with this added despite the odd green hue.
