Mining + Skinning + AddonFollow

I have mining and skinning, and i use the addon "Auctioneer". Its just when some n00b put rugged leather up for 999999999999 gold it says the average price of rugged leather is 2.052.424g. (2 million). Is there any way to prevent this?

Auctioneer works best when you have gathered price data over a long period of time. It works off median prices, not average - so once you have gathered hundreds of data points the outliers will be removed.

In the meantime you can reset the prices for one commodity.

The documentation is not total up to date but if you combine the forum posts with the release notes from http://auctioneeraddon.com/ you can figure things out.
