Being a dutch auction means that the tickets are sold at the lowest price of the succesful bidders. There for if 5 people bidded for one each from £1, £2, £3, £4 and £2000 respectivley, then the price for each one should be £1 as its the lowest suceesful bid. So at the minute they are £60 each.with 3 people bidding for one each.
