After the bidder puts a maiximum of £2000 on how does it jump from £6 showing to £110.00 showing?
Do you use ebay much? The price displayed (and that is the price it will eventually be sold for) is a fixed jump up from the second bidder's price. As an example:
I put a item on ebay - start price £1. At that price bids must go up in increments of 10p
Bidder1 comes along and bids £1.01. That bid is not accepted, because it is not high enough to meet the next increment.
Bidder2 comes along and bids £5. That bid is accepted, and the price goes up to £1.10 (the next increment)
Bidder1 returns, and bids £1.50. That bid is accepted, so the item has gone up to £1.50. But Bidder2 still has a high bid on, so the displayed price goes up to £1.60 - with Bidder2 still as the high bidder
Bidder3 comes along, and is really interested. He bids £10. That bid is accepted, so the item goes up to £5 (the high bid of bidder2) + 50p (because, over £5 the increments start to go up in 50p jumps). So it is now displayed at £5.50, and Bidder3 is the high bidder
Does this help? I am assuming that, over £100, increments are £10, because I've never bid that much on an auction...
