The basic logic is that you can find people from all over the world through internet than just from the locality of the physical store. So it is more easy to do business. But, the risk is that you neither see people face to face nor can prove that we are true guys, so it will take time to earn the trust of the people. Once you earn the trust then no one can stop you. You may be able to earn extra mmoney from the revenue of different ads. Also you get more display place in internet than in the physical stores.
