I like to post twice a day, listing all auctions for 12 hours. One of my postings occur when I wake up at around 5:30 AM, and the other occurs when they expire, at around 5:30 PM. This allows me to always have my auctions up, and I am the cheapest for a short period of my server's peak. If you are unable to do this, a 24 hour listing, posted during your server's peak period will do just as well. Following this strategy allows me to keep my input minimal, at about 10-15 minutes per day.
It’s a name lovingly given to me by my little boy, when he discovered I owned 1/4 of the wealth on the largest server in the EU. I’m proud of that, not arrogant. You can be “royalty” too if you put the effort in and refine your skills. One day, someone will become the Gold Emperor, and I will be extremely proud of them. That’s why I created a Hall of Fame, so you can journal your way to the top, see how far you’ve come, and be inspired by other member’s progress.
Lightforged draenei - "For untold millennia, the Army of the Light waged war against the Burning Legion throughout the Twisting Nether. The draenei most committed to their long crusade would undergo a ritual to become Lightforged, infusing their bodies with the very essence of the Holy Light. After finally achieving victory on Argus, the Lightforged Draenei have undertaken a new mission: protecting Azeroth from rising threats and helping the Alliance push back against Horde aggression."
If i start on a new realms, I am farming a lot of transmog from classic and Burning Crusade Dungeons and Raids. In the beginning, i start to post them if they have at least a DBRegionMarketAvg (Average value of an item on all EU realms of the last 14 days) of 500 Gold. All the other items get vendored. The time you hit a stock of 1000 Items, my value treshold raises to around 2.500 Gold. All the items below that value get vendored aswell. Newly farmed items that are above these treshold will be listed. Why? If I start over somewhere, I want to get a certain amount of gold quickly. Cheap items are great for that. Later on, to save time, Quality is better than quantity. As mentioned above, re-posting the items on the auction house takes quite a bit of time. At this point, I can recommend you the TradeSkillMaster AddOn, it makes your auction house work really a hell of a lot easier.
