The most basic answers are...cooperative marketing and selling and backend follow up by TriVita.
TriVita Business Affiliates don't have to sell product because TriVita does the selling. They run infomercials on television and radio every day. In fact, one of their infomercials is one of the all time longest running infomercials, the Sublingual B-12 infomercial has been running for over 9 years and has been instrumental in the sales of over 11 million boxes of the Sublingual B-12. They do massive print and internet advertising. And gain 500-1000 customers daily.
After they get the customers, that's where the cooperative marketing concept comes in and where we can begin building a business. TriVita allows us to reimburse the cost of advertising and through that method gain the profitability rights to their customers. It costs them $50 in advertising for each customer they acquire. So for $50 I can gain a share of the purchases that customer makes for life.
Then comes the follow-up. TriVita communicates with their customers (my customers) 18 times yearly. They send emails, they send catalogs and VitaJournals, etc. They frequently remind the customers in a friendly manner that they are concerned for their health and can help them on the road to wellness.
