How you sell your items in the WOW auction house can determine how much gold you make. Always research the market of your items before you put them up for auction. If your market is highly competitive you may want to set the price slightly below your competitors. That way you know it will sell. If your item is in high demand and you only have a few competitors then it May be safe to set it above your competitors. Chances are theirs will sell first but yours should sell soon after. Most people looking to buy items in the auction house want them right away. Don’t bother trying to get people to bid, just set a good buyout price.
Taking over a market in the auction house is a good way to make some gold in Warcraft. The idea is to focus on one particular item and buyout everybody selling it. Then you have control over the market and price of that item. Taking over a market in WOW takes investment gold and a close eye on the market so you can buyout any competitors. I would recommend using this strategy in a semi-competitive market. If you try taking over a very competitive market then you will need to constantly pay attention to the market and be able to buyout everyone who tries to compete with you.
