A lot of people wonder why they should host a party when they can just go to their local store and buy the products they want. Well, there are a couple reasons for hosting.
Knowledge - Depending on the store you are going to, and what you are looking for, the sales staff don't know about the product. At a home party, the consultant is specifically trained to tell you about the product, and if they don't know, they will find out.
Experience - At the store, you may not be able to actually experience the product - smell, touch, whichever. At a home party, you get to experience the product.
Free Product - What store is going to give you product for free when people purchase? I know I don't know any. When your Gold Canyon reaches $150 dollars in sales, you start earning free and discounted products.
Discounts - Your guests get discounts on their purchases too! Most stores don't do that just for attending!
