Making Loads of Gold from TBC Trade Goods (For Both Cata & Mop)

If you haven't noticed, most TBC trade goods prices are even more expensive than their Cataclysm equivalents, making them extremely good for gold making. It's often wise to farm the reagents yourself, because some Primals cost even 200g each, like Air and Water(Retail Prices sells for even more on private servers). But if the reagents sell for more than what the product itself does, assuming you are not the only one selling it, it's often a better idea to sell the reagents instead.
