The net is just massive. Bigger than you or even I could ever possibly imagine.

I believe it will at some point become the largest marketplace in the world. Brick and mortar stores will become out, left to become nothing but warehouses for products decided to buy and sold online.
Amazon isn't only the biggest retailer online, it is these days the largest retailer in the world.
One of the reasons for this is they have opened their doors to the public, making it possible for anyone to promote or affiliate market something of their choosing.
And then there's Amazons Kindle Direct Publishing, in which anyone with an idea could write a eBook about it, throw it up in Kindle store and profit from it.
If you have been thinking of a method to make money online (simply click the following site), selling eBooks on Amazon is an excellent spot to begin. Not only is it extremely simple (all you really require is a word processor as Microsoft Word), it's very cheap, even if you opt to outsource.
But in case you decide not going the outsource path and do all of it yourself, you could possibly have your book on Amazon and earn money without spending a single cent!
