The Home Party model has been used successfully by many companies and will certainly be used in the future. This book, by Karen Phelps, was written to teach the basic skills for booking and conducting home parties as well as how to follow up with the hosts and customers after the event.
Most home party companies deal with down lines and commissions and minimum quantities sold, etc. This results in high prices for the customers, because there has to be room in the pricing to pay out commissions to you and your sponsors.
But, if you do this on your own, you get to keep all the profit. This book will give you the confidence to conduct your first home party. After the first, it gets easier and easier.
