Could Costco sell AquaDx™ Water Sensor? (the single use PASS / FAIL one seen on TV) And can CVS sell it? And what about Walmart? Can they sell it? Could it be sold in Publix? Home Depot? ACE? Walgreen? Kroger? I'm referring to the PASS or FAIL single use WATER SENSOR to check water before ingesting: http://www.cdxlife.com/cdxshop/cdx/aquadxsensor1.html 2-Pack AquaDx™ Water Sensor
