There are many enchanting recipes available for sale at any given time on the Auction House, all going for various prices depending on your server, and you can spend a fortune trying to collect them all. While many of the most profitable recipes are ones that can't be learned from a trainer, they're usually very power leveling expensive to buy on the AH. The important suggestion is that you don't buy any enchanting recipes that can't be learned from a trainer until you reach top level. They will be worth purchasing once you reach top level, but at the same time there are other, easier ways to make a profit.

 

As an enchanter, you will be able to disenchant any uncommon item, that is, items whose names are colored. At early levels, most of your profits will come from disenchanting green items, the most common of the uncommon item types. Going to be from disenchanting quest rewards and other soul-bound items that are useless for your character and then selling the resulting enchanting materials on the AH for gold is your first and most important form of income while power leveling enchanting. For example, if you are playing a Hunter and a quest offers a choice of rewards of cloth armor, plate armor, or a staff, you are going to want to disenchant whatever you choose because none of those are useful to your power leveling. Because all quest rewards are soul-bound, you would otherwise have to sell them at a low price to a vendor, and can almost always earn more by disenchanting it and selling the resulting mats on the AH.

 

Enchanting materials require zero deposit cost to post on the AH is one of the best parts of the enchanting profession, so you don't have to worry about losing a deposit if your items don't sell. If your old gear is soul-bound to you, every time you upgrade a piece of gear, you will want to disenchant it so you can and then sell the resulting enchanting mats on the AH for gold, just like unwanted power leveling quest rewards. Never undercut competing players' items by more than one silver, because doing otherwise just cuts into your profits, and even if your item doesn't sell, you won't lose any gold to the deposit cost and can just repost it.
