Executive producer Christa recently got a call from a water-testing company claiming she had missed her appointment to test the water quality at her home. At first, she thought it was a scam marketer. But it turns out her husband Mike had scheduled an appointment without telling Christa.

Mike is a marketer's dream. He doesn't like to say no, and once even signed up for a credit card the family already had -- because someone asked him to!

When she got home, Christa reminded Mike that back in May she bought her own water-testing kit -- the Watersafe All-In-One Test Kit. Consumer Reports also recommends this particular brand.

The complimentary water test the marketer was offering Christa likely would have involved a hard sell in the home. As Clark says, they practically convince you that if you love your children and want them to stay healthy, you must buy their product.

As a reminder, tap water is generally safer than bottled water because the supply is checked multiple times a day. The bottled water industry doesn't have such strict regulations. Tap water is also a lot cheaper at less than a dollar annually vs. up to $1,400/year for the bottled stuff.
