If you don't know what arbitrage means: The simultaneous purchase and sale of an asset in order to profit from a difference in the price. It is a trade that profits by exploiting price differences of identical or similar financial instruments, on different markets or in different forms. Source investopedia Well, I was trying to use this method of business on a couple of websites Craiglist & Fiverr. What I did was put a listing up for as a CV/Resume writer offering to write or rewrite for a price. I would use Fiverr to source people that can actually do this work for a lower price than I was charging. Working as the middleman basically. I found out about this method from another forum, can work for you if you find something people want. Its greet to gain a little cash to grow. The problem I ran into was the fact that craigslist is dead in UK, it does not have much attraction over here only had about 3 sales No point trying to post in the states because that don't work. After that I don't want to give on this whole arbitrage thing. Have any of you ever used this method? What selection of services do you use? Is Craiglist useless everywhere apart from the US?
