Clean Water, Dirty Tricks (38x4)

Uitzenddatum: Jan 28, 2011

Marketplace goes undercover to expose the techniques used in door-to-door sales of water purification systems -- devices that can cost thousands of dollars, but which most people simply may not need. Co-host Tom Harrington investigates the scare tactics used to entice people to buy -- and meets an elderly woman who spent $3,500 on a purification system.
