OOPS!

I've seen a lot of silly blunders on the market (and made a few myself) but the one I found in my wallet transactions log today was one I've never seen the likes of before.

This guy sold me 3 different modules for 0.01 ISK each, far less than my buy order prices. Making a typo on a sell order I can understand, it happens. But for 0.01 ISK, on 3 orders in a row and all the same type of module (faction BCS mods)?

Really stupid, really drunk, a mean brother/friend and a misconfigured bot are about all I can think of that could have caused fail of this magnitude. Any other ideas?
