I put up 7 gold subs for sale, and they sold for: 7,499,996gp.

I have no idea how this happened. I can't say I recall putting in such an "odd" price. I could believe my user error if it were 7,500,000 exact (I may have mistaken the listing for being something else), but being 4gp off or selling them 1,071,428gp each is really off. I'm pretty positive I put these in those 3,500,000 each, so I'm not sure wtf happened. Or how I "typed in" 7499996. Maybe I did and I was half asleep when I did it.

Is it possible for a mod able to look at AH history to see listing activity, or when "time" this may have happened? I'd like to make sure nothing fishy is going on with my account... thanks.
