Auctioneer/Auctionator
Getting yourself a good Auction addon is extremely vital to making gold in World of Warcraft. These add-ons allow you to scan the Auction House and use that data in a number of ways to amass a fortune. The Appraiser feature really helps when it comes time to sell materials you’ve gathered or items you do not need by finding the best prices on your specific server and undercutting the competition. The best Auction House addons are Auctioneer and Auctionator.

Bagnon/Adibags
Keeping your bags organized can be a huge time saver when it comes to making gold. The games default UI separates all of your content into multiple bags which makes finding things a pain at times. Bag addons, like Bagnon, allow you to view your entire inventory all at once without having to sort through different bags, and some, like Adibags, can even automatically organize the contents by category. While these add-ons do not directly help you make gold, they definitely help with keeping your inventory of gold making materials more organized and thus speeds up the process as a whole.

VendoMatic
You might not think all those gray items filling up your bags would be worth the time to sell but when sold in large chunks they can mean serious money. Of course, having to sit there and manually sell each item one at of time is a real time sink. Add-ons like Vend-o-Matic make things way easier by giving you a single button to press to sell all gray items at once. You can even set it up to sell automatically as soon as you talk to an NPC.

One of the most rewarding aspects of WoW is after you’ve sold a bunch of stuff and go into your mailbox to collect all the gold.
