I’ve never actually used one of these sniper services but I would imagine you would have to state your top dollar (otherwise it could be a pretty expensive bid) ![[New Laugh]](graemlins/newlaugh.gif)
and presumably whoever gets in first, before the auction ends, with the highest bid wins.
Not sure what the order of the bids would be in the unlikely (but possible)event of a few people using the service for the same auction with the same highest bid! ![[Puzzled]](graemlins/puzzled.gif)
