Make money on the net

How about making money from a website? Doesn't even have to be your own website.
Maybe you don't have anything to sell? Well then why not sell someone else's products?
Or just talk about stuff? Or you do have stuff to sell but don't know how to build and promote a website?

Sometimes, apparently you can buy an amazing product off someone, they'll build you a website and all you have to do is sell their amazing product to other people like you, whilst you relax on the beach, drink cocktails, make money whilst you sleep and generally watch the money roll in...
Hmmm, all sounds a bit too good to be true, doesn't it?
