1. For maximum gold, your very first character must take on at least 1 gathering profession, preferably Mining as it supports 3 crafting professions.

2. Auction every single item that is not gray. Mass mail everything to an Alt to save time.

3. All the green items that you find should be saved and mailed to an alternative character, when you have collected bags full of them, you should tip (generously) an Enchanter to disenchant them. Shard and Dusts are selling at an incredible rate and I can only foresee even better outcomes when the Wrath of the Lich King comes out.

4. Using addons, the Blizzard interface is fine, but addons that adds additional information such as Gatherer and Auctioneer helps tons.

5. Become a supplier for "crafters" in top guilds in your Realm. These chumps go through mats like water, they are constantly in demand. Even selling them at a lower price will benefit you in the long run.

6. A tip when mining, Silver refill Tin nodes. Gold refills Iron nodes. Truesilver refills Mithril nodes. So if you are just looking for Truesilver, you must NOT ignore the Mithril nodes as this will reduce the overall chance of Truesilver node spawns.

7. Take on the profession Inscription when Wrath of the Lich King launch. New professions will be in very high demand with little competition.

8. Selling seasonal items. Take a look at the Blizzard's calendar and look for upcoming in-game events. You would be surprised to see the demand for certain items jumps up to 10x at certain times of the year.

9. Understanding supply and demand. There is a given supply for every item in World of Warcraft, and there are also a given number of people looking for that item (demand).

Let's look at this example, a server with 85% population being level 70s, the prices of some lower level items might be insanely high, this is because not only are these items in demand by lower level players, but also high level player's alts. Depending on the item, they could also be in demand as mats for leveling professions.

10. Have fun with the game, World of Warcraft is a game after all, don't get so stressed up sometimes because you did not farm enough gold, just stay consistent and find a way to farm gold that you enjoy.

These 10 Gold Tips have certainly helped me tremendously in World of Warcraft, I hope it does the same for you.
