Network marketing businesses are either legal or scam. When a network marketing business requires you to buy costly packages, but earns you less, it is often a scam. When it is otherwise, it is legal.
Despite the spread of networking scams, network marketing businesses still thrive because of quality products, good incentives, flexible working time and affordable investment.
The common products who worked around the network marketing are beauty, health, clothing and underwear, kitchenwares and insurance. Except insurances, those products were often small and medium home-based businesses that target women market.
