And another thing... I wouldn't bid on the last second to go. I don't know why people do it but it's a recipe for disaster... If you have a slight internet problem and it lags, you're screwed so always bid early in the knock out rounds... It won't make a difference because if the other player bids then it will go to the next round, it's just to be safe from any lag.

I have lost quite a few auctions from bidding last second after internet lagged a bit
