In World of Warcraft there are a lot of ways to make gold but not all of them are very time efficient. If you want to make the big bucks and work your way toward the mythical 1 million gold cap, then you're going to want to install a few tools that will help you along your way. These add-ons will do just that.
1. Auctioneer – The classic auction house add-on is called Auctioneer and will provide the kind of long term strategy boost you need to be effective in all aspects of the AH. From daily scans to easy checks for low priced value goods to the extra built-in adds on like disenchantrix and bean counter, Auctioneer is a must have for any gold hound.
2. Auctionator – This add-on is very similar to Auctioneer, allowing players the ability to scan auctions and effectively research the different prices that each item will sell at in groups. Instead of single items, you'll see every stack currently selling at a given price range, allowing you to buy them all out at once.
3. Market Watcher – Another auction house scanner, Market Watcher allows you to research the values of specific items on a watch list which you can then plot and chart over a time period to see how those values rise and fall. There are websites with similar data charts, but Market Watcher lets you personalize your data more easily.
4. Postal – Postal is a tool to make your mailbox more efficient. It allows you to open more mail at once, access more mail when you have tons of incoming messages and expand the sending limits when transferring items and gold back and forth.
5. Gatherer – Gatherer allows you to create and follow plotted points across a major zone to find verified ore and herb nodes. This also works for fishing and skinning, though the data is not nearly as accurate with either of those professions as with the two main gathering profs.
With these tools, you'll be well on your way toward the massive piles of gold you've always dreamed of. Of course, you'll still want to learn how to use those tools effectively, and that is going to require a decent amount of additional work spread out over the course of a few weeks or months, but for now, just getting everything installed is a good start.
