you really need to put a cancel button in appraiser, i put some ammo in and didn't notice the stack defaulted to 1 and i hit post. i couldn't stop it, i closed the window went to a different auction house and when i opened the auction window it started posting them 1 by 1 again, i tried posting something else, i even tried logging out and back in wtf! if you think thats messed up i had to take them out of the mailbox too.
