I will let iamsonic go over the rules with you if youd like. I think if its something you contact staff about first and discuss it, it could be brought back up.
My two cents is, and the problem many forums have seen in the past with group buys is if the supplier doesn't come through the organizer of the group buy (you in this instance) tend to take no responsibility and poof lots of money is gone and no one to blame. The reason we stay clear of most group buys is not that we want people to not get good deals but it deters a large chance of several people losing money.
