I was just wondering this thing about setting up high CPC by mistake.. We should be extra careful while dealing with those decimal numbers.
My suggestion : Put your time in a possitive thinking ! Think that you learned a very important lesson that cost you $86.40 !
Thanks cdx...and everyone. I've learned a lot from this incidence. I believe events like this are meant to make us stronger and wiser. Things will only get better from now on...
