This used to be an issue, but, there are internal functions to help ensure that only the 'real', valid auctions are counted. The developers take care to help ensure that people are not able to 'fool' the statistics by placing some items on the Auction House for outrageously high or low prices. All are extremely useful when deciding whether to pick a certain quest reward, purchase an item directly from another player, et cetera. The user can decide to show the Market Price, which uses Probability Distribution Functions from all active statistic modules to recommend a purchase/sales price, numerous outputs from each of the Statistic Modules, and the vendor sales/purchase prices. Outside the Auction House, users may mouse over item icons or links to bring up an extended tooltip, which will include a fully configurable set of data. When starting out, users should ignore the pricing recommendations until they have scanned the Auction House once or twice a day for at least a week that will allow Auctioneer to gather the data needed to make accurate recommendations.

Doing so ensures that an accurate price history is recorded for all items, even those a player does not currently have in their inventory. It is highly recommended that, even when using partial scans, a full 'slow' or 'fast' scan should be completed roughly each game session or two. Partial scans of a single item may be done from Auctioneer's 'Post' frame or the 'Appraiser' frame, which will quickly compare the price of the item being placed for sale to the current listings/auctions of that item. Both scans obtain nearly the same data the 'GetAll' ignores the name of the seller, which allows its faster speed. Each client is limited by Blizzard to using the GetAll command once every fifteen minutes. When using the 'fast forward' button, from the 'Scan Control Console', your client pulls the entire Auction House contents at once, so the scan is extremely fast, taking roughly three to five minutes to complete the scan and the statistical processing. The first method, used when clicking the 'Scan' button or the 'play' button from the 'Scan Control Console', located in the upper left of the 'Browse' frame, takes about 10-15 minutes, all depending upon the number of items/pages on the Auction House at a given time. There are two different scans possible, a 'slow' scan using /Auc Scan or a 'fast' scan using /Auc GetAll. Scanning is initiated by the user and no further action is required until the process is complete. Auctioneer obtains its data through scanning the Auction House.
