I am so so sorry....
Oh sorry you are right.
How should we do it to be fair?
hmmm.. not sure. It's your auction, hence your rules and you will decide what should be done & how.
Proposal: Let the announced winners get those specific numbers & the rest of the bidders -maybe- offer them the chance to purchase another # at a fixed price. (or something like that... dunno)
Just a suggestion... what do the others have to say?
