No. One of the greatest features of Network Marketing is that success can be achieved using a wide variety of methods. You choose the methods that YOU are comfortable with; whether that means internet, direct mail, distributing catalogs, telemarketing, meetings, one-on-one, in-home parties, via fundraisers, commercial accounts, and so on.
They might do this through door-to-door sales, through the internet or by having parties in their homes.
Network marketing is a legitimate business. While some people do make a lot of money through network marketing, their financial benefit is always the result of their own dedicated efforts in building an organization that sells real products and services. Pyramids are illegal and are based on taking advantage of people. Door-to-door sales (or D2D) is a direct selling method, a canvassing technique that is commonly used for sales, marketing, advertising, and campaigning. In D2D, sales reps visit potential customers in their homes and convince them to buy products or services.
