I've been raging.
I've done it a couple times now, one miss click a few pixels away and I spent 50K that I didnt need to be spending.
Then it needs to go back on the AH, for a price that will sell, and usually take a loss on the 10% selling fees...
Please, move one to the top, or put a "You sure you want to buy now" pop up.
I think buying/bidding on something from auction house should have a popup notice.
