The Pura thing is getting pretty confusing, but they did show an increase in bottled water sales between their 2nd quarter report ending 3/30/2018 reported income was 287K and their 3Rd quarter 2018 reported income was 583K. Thats a 306, 000 increase from bottled water sales.
I do not see any filings that show owner or stock connections between Pura and ALKM. Since we know Pura has been buying their water products from ALKM. I am going to follow the money and invest in ALKM. IMO
