I feel we could all benefit from having a confirmation text box appear after attempting to purchase an item on the Auction house. If purchasing a lich robe for 500m the buyer will hit the purchase button on the AH at which time a confirmation text box will appear and confirm you want to purchase a the lich robe for 500m. It will save the dev team having to undo miss clicks on the AH in the future. This is pretty standard protocol for most AH transactions.
