Yes, you can! When you do this, we call it "Retail Profit" (Not to be confused with the Retailing Bonus).
*Only Brand Affiliates are authorized to resell product.*
Retail Profit is the difference between your costs (including Member Price, taxes, shipping, etc.) and the price you sell products for. You handle all Retail Profit earned outside of Nu Skin’s systems. You may establish your own retail prices for products and may keep all of the profits you earn from selling the products to your Unregistered Customers.
