Sounds a lot better when you explain it like that. And, yeah, I don't really think anyone of us, except for 7bit maybe, have enough information to direct our complaints at you.
Feels like this thread is a "shame on you Kayliss" kind of thread, so I agree with you that the best would be to solve it between you guys. Some of the information in here is quite useful though, so maybe a purely informative thread, without anyone's name to be shamed, about some kind of group buy etiquette would've been better. (This opinion may not really be relevant to this discussion, though.)
I guess the most important thing for everyone to learn is that communication is king. :>
