I wondered how Duke outbid me for a chip, by 1 cent. It didn't make sense.

If he bid $10.01 on Monday, say the auction was it 8.00 and I bid $10.00 on Wed. then he has the winning bid because of the date, at less than a bid incriment. (gee thanks guys, you probably explained this before and it went through my brian like a sive)

Meanwhile.. why would someone want to bid against themself if they were high bidder?

If it's an "insurance" bid, then it makes sense that eBay will raise it to the next proper level. It looks like someone is playing games with finding Proxy bid amounts?

I still don't understand the theory that someone tried to tell me I could bid on items and not win them, but find out what the high bid was by increasing by smaller numbers. It has to be 50c over the last bid, so at that point, the bidder must eventually pass the former high bid and become the winner.

It doesn't work!
