Fulfillment by Amazon - Not sure if this has been discussed before

Is there anyone on here making money via FBA? I've started writing an article on it (in progress) before realising that it's a perfect fit for this subreddit. There's quite a lot of people over at /r/fulfillmentbyamazon living off this, completely online. Anyone here got any experience/stories on it that I could put into my article, or any ammendments you think I should make?
