Consider if you bid a minimum amount on everything (except rockets or things you don't like), so you bid on say... 250 lots all at $1, maxxed out on quantities. You would lose the majority of the bids, but you would still win close to a third of the lots, considering you upped the next possible bid to $3 or more, where the item cost vs. value starts to even out, and less people will be interested in the item. You end up getting the best value by being the first to bid.
This example only applies to singles, but there is an amount for 5ers, boxes, etc. that you could determine.
And this doesn't at all take into account human stupidity, determination, overbidders, etc.
