Similar to other buildings in your Garrison, the Shipyard can be turned into a nice and steady source of gold. This gold making method is pretty simple once your Shipyard is up and running, and your fleet is complete. But sadly, not many players bother with it, and they are at loss because of it. As a general idea, there are Naval Missions which offer ... Read More »
Some players even turn this into their profession by systematically "plundering" vendors in the game world and then selling the items on the auction house at a significant markup. The reason why this works (even for items which are on unlimited supply at vendors) is, that many players don't want to spend time traveling to specific vendors to get hold of a recipe or skill book. They would rather pay a slightly higher price at their local auction house. In some sense, they use the auction house as a "super market" or "convenience store". So it is completely reasonable and legitimate to be the supplier for this convenience store and make money out of it.

 Mag'har orc - "For untold generations, the orc clans of Draenor battled one another in endless war. But when Gul'dan offered them the blood of his demonic masters, the disparate tribes of Mag'har—the orcish word for "uncorrupted"—refused the dark bargain and banded together to drive out the Burning Legion. United under the leadership of Grommash Hellscream, the Mag'har pledged to one day repay Azeroth's heroes for aiding their cause. As war against the Alliance intensifies, the Horde must call upon the might of the Mag'har to seize victory."
AWESOME spot.. if you are a druid, here's why.  This spot takes place on an island in the very north part of Stormheim, which is surrounded by water.  In this water are 2 groups of crabs that roam in packs of 12.  Each of these crabs can be skinned for scales and with the usual perks I mentioned in the earlier skinning spots.  (See spot 13).  The only catch is sometimes the crabs are very far apart and require some travelling to get to.  Druid travel forms not only have increased swim speed, but the wild charge ability allows you to swim 150% faster for 10 seconds, all the while replenishing your breath meter.  Pretty cool right?  I found that druids are AWESOME for farming this spot and can easily outclass other farmers here.  It's a druid spot that limits the competition – while ensuring you have the most uptime.  Very cool.  Gutting and level 3 stormscale skinning recommended.
Crafting is the art of buying materials and turning them into other materials or finished products that you can sell on the Auction house for a profit. It is one of the most consistent gold making methods in the game, but generally requires you to bind up some amount of capital in your inventory in the form of materials and finished items before they sell.

Keep in mind that these quests are optional, and are not necessary to continue leveling and capturing companions. They are also account-wide, so if you complete the quest chain on one character, you will not be able to complete it again on another. However, any progress that you've made will be saved and you can pick up where you left off in the quest chain on another character. The dailies that you've unlocked will also be accessible by all your toons.

Level 120 comes and goes. Island Expeditions have unlocked, but it turns out they’re not much fun, and the most rewarding versions are only accessible to premade groups. You turn to Warfronts only to realize they’re not available this week. Fine. You can always grind out better gear. Except as you do, you notice your new gear has higher Azerite requirements than your old gear, which means your shiny new items have fewer unlocked traits than what they replaced. Discouraged, you decide to roll as one of the cool new Allied Races. Except you can’t because they’re all locked behind reputation grinds.

These are Warlock- and Mage-only skills which can net you some money. It's not much, but a few gold is worth it. Note that Mages have an easier time with this than Warlocks as Warlocks need to be at the location for the summoning and need an additional person (a 3rd) for the group to help out with the summons. Mages only need the reagent to open the portal. While the Warlock doesn't incur a cost (except the loss of a soul shard), the Mage will typically be more successful at finding employment using this method.
Most of the players make the mistake of only listing 30-50 transmog items on the auction house and then hoping to get half of them sold until the next day. Me and a lot of other gold farmers and transmog sellers do have 3.000-10.000 items on the auction house across various realms. It does not mean you have to do it that way – but if you have 1000 items listed, chances are higher you can sell up to 10 per day. With only 100 items listed, you have to be lucky to sell one. Of course, the sells are not guaranteed if you post more items. But i’m sure you have a lot more fun if you open your mailbox and 10-20 items are sold
