Shuffle materials, the act of turning an item into a more profitable one. The most profitable and reliable methods involve proffesions.
Mageweave cloth -> white bandit mask -> DE -> profit.
Ghost iron ore -> prospect into blue and green quality gems
Blue gems: Cut, AH
Green gems: Cut, AH, cut into green and blue quality items.
Green/blue items: Disenchant, AH
Enchanting mats: Enchant vellums, AH
Enchanted vellums: AH
= Profit
At any point in this chain above, you can exit and AH if the following method of transforming the item is not profitable. You can also buy in at any point and continue from there. For me, selling and cutting green gems are more profitable than turning them into green items for DE. So i sell the gems, buy enchanting mats and use the enchanting mats to turn into enchanted vellums.
