A few times I slightly overpaid, but one time, when 100k certainly was more for me than 1 or even 3M is now, I paid I think a bit under 400k for a 1k scroll while bidding for Utsusemi 2. It was rather funny because I think I got an IM at that moment, and for some reason, it likes to activate the mouse cursor which was at the time located over that cheap'o scroll. ^^;
I didn't even send them a message, but I did send them the scroll back!
I don't mind that they didn't send me a message even; it was my mistake, but I personally would still send the money back even if it was 99,999,999 Gil. Though at that point, I might consider reporting them to the STFµ first, since that might be just a tad suspicious...
