It's almost like the original online low dollar bidding site, BeeZid...You buy so many bids and then bid in penny increments....
I watched a couple of items on BeeZid and the bidding went on for hours between a half dozen people...The observed price was really low, but to have bid for that long, the cost of the bids had to have been up there..
Legal, yes....Ethical, not so sure...Cost effective, rarely..
