They have discussed offering young adults free T-shirts and special discounts on Xer-Wise equipment if they will agree to hype the benefits of the MuscleMaster in Internet chat rooms. They are even considering setting up a program in which customers get commissions for directing friends to the Xer-Wise website. If they adopt these strategies, Tom and Melody would be utilizing: 1) secondary marketing. 2) viral marketing. 3) unified marketing. 4) extended reach marketing.
