The simplest method of generating an income is to buy products from Amway at their base wholesale price, add a markup, and sell them directly to a consumer. In general, Amway Business Owners (ABO) have the right to sell Amway-sourced products at whichever price they choose. The recommended markup on Amway manufactured products varies from 20-35%. In many markets Amway also makes available products from third-party manufacturers. The potential retail markup on these "catalogue" products is usually limited however, and they are generally made available for the personal convenience of Amway business owners rather than for resale. There are a number of exceptions to this, including XS Energy drinks and Emma Page Jewellery.
