		_TRANS('WECN_Help_WhyGlobalPricesAnswer') --Server specific prices can be useful if your server has prices which are far removed from the average, but often these prices are based on many fewer data points, causing your server specific price to possibly get out of whack for some items.  This option lets you force the Wowecon stat to always use global prices, if you\'d prefer.

Even though these prices are hidden from the tooltip, they are still reported to Appraiser.  If you are not using the global price option here, you should check to make sure there isn\'t a hidden server specific price for your server, with just a small number of seen times.

This will generally only affect items that are slightly different from the normal base item, and have no, or very little price data due to their uniqueness.
