I don't use auctioneer to make money. I don't even use it as a price reference. The only purposes it serves me are posting large amounts of auctions with ease and finding the cheapest of an item that I need on the AH. I love the ability to sort by price per unit. You can really find some good deals.

I'm sure you can make money with it, because plenty of people do, but that isn't the purpose it serves me really.
