Hi - have been looking at bidding histories for items on ebay and have noticed that that starting price is often 99p but then the bids go up by £2 or so at a time, e.g. starting price 99p, 1st bid £2.50, 2nd bid £3.75. Why do the bids go up by so much and not say 50p at a time, especially the first one when there is no bidding war taking place - does any one know?
