eBiz is offering Computer Courses (Online Tutorials & CDs) for all major courses like JAVA, HTML, Programming, Networking etc for just Rs. 7000+ plus you can also earn money if you bring 2 more people under you. And its like a binary tree, the tree will grow on and you keep on making money and all good stuff. But somewhere I feels its crapshit, you cant offer good quality things for 7k, which outside take lakhs of rupees. So my friends are doing this but I am totally against it. How do I explain them that it cant work for long??
