Also, if the price of an item is fluctuating don't panic if you get undercut. If you are not out of selling spots just let them sit there. This goes well especially for crafting materials. It might take up to a week but then someone who's leveling their craft or who knows what buys the board near empty. So if you know you have reasonable price, just see through a week cycle or two. I did good money when I was leveling my retainer by alway getting same item. Partly it was because I didn't bother to raise his item level much so I was stuck with 30-35 hunts. Might not have been the fastest exp for her but for a while I had a steady supply of an item I sold on flat price. All of it sold eventually. Since I put it up as I got it it was in up to 5 stacks which I only combined if I ran out of sale spots.
