If you like Auctioneer’s sophisticated pricing, but don't have time to scan the AH often enough, this add-on is for you. It’s an Auc-Stat module that integrates WoWuction as a source of Auctioneer price data.
Install the TSM App from http://www.tradeskillmaster.com/tsm_app and set up WoWuction.com updates in the app. Then open your Auctioneer settings (“Configure” button in the AH) and enable WoWuction as a stat module. Now you’ll have market-price estimates that take into account *all* recent market activity, even what happened while you were offline. Enable other stat modules such as Auc-Stat-Purchased and Auc-Stat-ILevel, and Auctioneer will look past the buyout price to give you even better estimates. If you’re a crafter, you can put these numbers to work for you by choosing Appraiser as your source for TradeSkillMaster costs and fallback prices, like I do.
Note that this app comes in two versions, and this one is for region-wide data. Install Auc-Stat-Wowuction-Xrealm for realm-specific data. Both versions can be combined.
