So at that point I decided to learn from it. I enter into a field of about 4-5 goods and I use a very similar method, I drive out my competition while stocking up, then make profit off the stock, then drive it higher for even more profit. Others begin trying to hop on board and make profit from my efforts there- and then I start the process again, often demolishing them in the process. Not always, just often.
And that's when you ask your crafter friends for a discount. Seriously if you're having fun that's great but if you think you are controlling anything you're deluded. It's not that hard to craft things, if the MB is expensive you go ask personally to a crafter.
