The easiest addon for making lots and lots of WoW gold! Adds new information to the tooltip for each item, showing the prices you have bought and sold items for, along with their current average price, a ratio showing your auction selling success rate and the number of days since your bought/sold this item. Can search for cheap bids or buyouts and selling items from your bags has never been easier, with prices being suggested based on your buying and selling history. Undercut your rivals, and see which items are not being auctioned by anyone else, letting you corner the market. Sell as a full stack - or break it down into individual auctions.
Colorizes items that you already know in default merchant and auction frames.
Figuring out a good buyout price when posting auctions can be tedious and time-consuming. If you're like most people, you first browse the current auctions to get a sense of how much your item is currently selling for. Then you undercut the lowest price by a bit. If you're creating multiple auctions you're bouncing back and forth between the Browse tab and the Auctions tab, doing lots of division in your head, and doing lots of clicking and typing.

Market Watcher is an addon that scans the auction house and records data for specified items and assists in daily auction house shopping in general. When the addon is set to record, a price history can be displayed to assist in determining a value for items of interest.
What makes Market Watcher unique from other auction house addons is that it records multiple scans instead of just the most recent. This obviously uses a great deal of memory, so only scans of items specified by the user will be recorded. The saving of multiple scans allows for a more accurate determination of value, and allows the addon to deduce if some auctions were actually sold, so you can see which auctions are actually selling as opposed to basing a value off the prices of auctions that may not be selling at all.
TradeSkillMaster is a MODULE BASED system to help both NEW Auctioneers and the MOST ELITE AUCTION GOBLINS manage everything related to the Auction House! Our goal is to work hand-in-hand with our community to develop an all-inclusive suite of modules that, when used together, follows our users through every single auction and crafting related function, making them as much gold in as automated of an environment as possible while still following blizz Terms of Service very closely.

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.
