The next thing.. episode 2

Markets fluctuate all the time there is no reason other then demand. You can't control what people want but you can have the items for them to buy ;)  The best thing that you can do when a market is change the materials to a better market item. Lets take a look at what is known as a shuffle. We take a stack of elementium ore stack is selling for 47g so if you have this ore you can sell it for that or you can prospect it and get some gems about 6 of them that are common green gems depending on what gems you get you can cut and vendor most of them for 9g each to make 54g that's a free 7g per stack based on that alone now you  could take it farther and use those gems with jewelers settings to cut into things like carnelian spikes to disenchant to get the materials.
