I can tell you that Jack did not pursue the retail (big box pharmacies) avenue because of the profit margins. The pharma companies wanted to buy big amounts of the product at deep discounts which would not be profitable for avVaa.
probably poor marketing by jack Farley. I will tell you this that from my personal experience they work great. No B.S. Maybe there has not been enough sold for return business to make a difference. but I believe when it does happen it will be significant.
