Auctioneer 3.4.2 mod.
This plugin provides you with in-game data on data that is collated by you at the auction house. You trigger the data gathering by either clicking the "Scan" button on the main page of the Auction House, or by typing "/auctioneer scan" manually.
It provides you with methods to identify the bargains at the auction house (the percentless and bidbroker commands) by identifying price trends and then finding items that will buyout or bidout for less than the trend data suggests should be it's correct price. By identifying these items, you can play the market. Buying low and then relisting at the market norm.
This plugin also provides you with a database of vendor buy and sell prices, what professions will use the item and stack sizes for a relativly large set (about 7000) of common in-game items. This data is presented when you mouse over an item, and the tooltip appears (Yes, even when looting)
I would like to personally thank Araband for the massive amount of work that he did getting this new version of Auctioneer out, and I fear that without his help, you would not be seeing such a great product as it is today.
I would also like to thank the many people who helped with the beta's bug testing, and numerous suggestions for improvements. We really appreciate the work that you've all done with the testing and appreciate you taking the time out to give us the feedback that we needed to make this release as good as it is. I know I speak for both Araband and myself when I say we couldn't have done as well without you!
