The company leaders think a big reason they're doing so well is because of the way they advertise.
Melaluca CEO Frank Vandersloot said, "You can't say much in a 30 second spot but when your friend, or mother, or family member, someone you trust comes and tells you this product is really good, it's really good. We think that's the way to get the word out and that puts a lot of pressure on us to have good products. People wouldn't say good things about them if they weren't good."
