First of all I hear all the time people contemplating of setting up a blog as they think it is too time consuming having to write content or hire people through Odesk or Elance for example. But the thing is you can go about this a few ways and I have listed this as follows..

WP Robot allows you to integrate all your Amazon, Clickbank, Ebay accounts etc and with a click of a button. You can pull in latest reviews and products from those sites to display in your own site/s. This means you are automatically getting the latest reviews and products displaying in your blogs without having to write new content yourself.
