Disclaimer: Part 1: If you buy the guide through the links on this page I do get a cut. Part 2: With the guide I have leveled one Rogue from 70 to 90, another from 1-90 (yeah, two 90 Rogues,) a DK from 55-90, a mage from 1-90, and various others. Family members have leveled an assortment of other characters, some with little gear, others with full heirlooms and Recruit a Friend (3x XP.) So I confess, I like this guide. We all do.
The most important step in being able to buy a mount and make other large purchases should be self-evident: saving. Economize as often as you can, and don't buy anything unless you absolutely have to. You can burn through hundreds of gold even before level 20 by visiting the auction house for new equipment at every opportunity. If you do so, over the long haul you will be left with very little to show for it. Before level 20, keep your eyes on the prize: getting that mount. The mount helps you move faster. Faster movement means faster killing, faster questing, faster quest turn-ins, and faster leveling. It is the most important tool to fast leveling you can get at level 20, and infinitely more important than getting your hands on that Left-Handed Vorpal Cleaver of the Zipswitch that you could have purchased at level 23. Stay focused.

On January 30, 2018 Battle for Azeroth was made available for preorder, coming with the unlocking of the four first allied races. With the announcement of the Collector's Edition and release date for Battle for Azeroth on April 5, 2018, Legion was the first expansion to be offered for free with a preorder. Battle for Azeroth is the first expansion to launch in the Americas, Europe, Taiwan, Korea, and Australia/New Zealand at the same time. Battle for Azeroth became the fastest-selling World of Warcraft expansion ever.
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.
Once you get to about 200g, the theoretical limit of your profit virtually disappears. You now have enough money to start mass buying and reselling those players' goods who undercut everything by an extreme amount. Enchant mats are still a very good focus during this period, especially essences and crystals. You can now afford to buy several maelstrom and abyss crystals and wait until prices fluctuate to resell for a profit. A major strategy you can begin to employ is the multi-character trading and auctioning. If you come across 5 abyss crystals, get onto one character during peak hours and advertise a price 25-50% higher than average. When no one responds to this, quickly switch to another toon and offer the same 5 crystals for 10% lower than before. This will help to raise the median price because other sellers see what they may be able to get for their good. While they are cancelling and reposting, take this time to undercut their new prices, which is now more than you ever could have gotten before when prices were low. If you master this with BoE epics or more rare items, then you can make differences of thousands of gold.
This is cumulative, as you take into account each failed sale as a loss. In the event too many deposits accumulate, you must decide whether to continue selling the item inflated by too many sales or finding of another way to dispose of it. One final tip: when you find that an item fails to sell in one AH, selling it on the other may finally dispose of it and get you your earnings.
