I did some searching online and both Xango and Juice Plus use Multi Level marketing. Which means they pay people to promote their product and give them a percentage of whatever they sell.
Not saying this is a scam but this guy mentioned both of them. He may be just trying to make a buck off of our problem.
I checked the prices and they both cost around $40. You'll go through that juice in no time and you'll end up spending a couple of hundred dollars.
