Another example of the power of promoters. Shade Clothing sells undershirts for women that are longer than normal for those that aren't interested in showing the world their belly button. It was founded in September 2004 and in its first year of business it sold more than $2 million dollars worth of modest undershirts.

Listen to this quote from Chelsea Rippy, one of the founders:

Our main source of advertising is women telling other women.

In addition to selling through traditional retail channels, Shade focuses on finding promoters and giving them the tools, and the incentive, to spread the word. They call them "personal shoppers." From their website, here are the benefits of becoming a personal shopper:

Become a Personal Shopper and:
• Earn 15-20% commissions on all orders placed through you.
• Earn commissions on client orders placed online using your personal shopper code.
• Offer your clients access to exclusive products and discounts.
•
Additional benefits include:
• Set your own schedule
• Your parties posted on the Shade Clothing website
• Sales materials from Shade Clothing
• Discount on product
• Exclusive access to the Personal Shopper Online Management System

In return, Shade gets literally hundreds of customers that love their product, telling their friends and associates about it. Hard to argue with the results.
