Trick Auctions

I'm describing this more as a warning than a way of making gold. I personally find it unethical but it's your call.

A number of people have started putting items in the AH – usually enchanting or tradeskill items - with a very low bid and a ridiculously high buyout price hoping that buyers will see a bargain and get so excited that they click on the buyout button by mistake

For example, as I write this there are Large Brilliant Shards, which normally sell for about 3 gold, on bid for 20 silver and on buyout for 99 gold. If somebody clicks on the buyout button without thinking they lose 99 gold and all sales are final. If you bid the 20 silver you will find that the auction gets canceled about 20 minutes before the scheduled end, so no bargains there.

Maybe the Chinese gold farmers are fed up with grinding :)

Be careful where you click.
