Network marketing is only workable if only you are selling consumable goods. But before you purchase anything pls check if there is other products which are similar or produce the same effect and thus comparing the price before you make any purchasing. Products like the magnetic mattress is not consumable and moreover its price is way above what u can get elsewhere.
For ppl who wants to know more about network marketing and its pros and cons, pls do some research first before you make any decision to join or to buy the product.
