This addon is very simple. Install it, and most items that can be sold on the Auction House will have pricing statistics added to their tooltips. You do not need to run auction house scans like other pricing statistics addons, nor are there any options to set. Just install it, and you're done.
Market data is compiled from all US Alliance and Horde auction houses by The Undermine Journal. Market data comes with this addon, and will be updated once each week. To get the most recent data, just install this addon on top of any previous copies.
The Undermine Journal is unique in its coverage of the Auction House. Along with this addon, there are a variety of tools available on the website. Market data with item and seller graphs over the past 2 weeks, along with market notifications delivered to your email, are two of our most popular features.
The data in this addon is averaged across all US realms in your faction (thus the "GE" tag: "General Edition"). To receive data specific to your realm(s), including the last time an item was seen on your auction house, and the most recent market price and quantity seen along with the average, visit The Undermine Journal Addon page for details.
