Steve,
He may have put in a higher bid, and the guy bidding after him kept bumping his bid...it would appear that the guy was "raising" his bid when in fact the later bidder was doing all the work...
eBay....
it hard to read anything from the bids(except feedback numbers)
3489 is a well seasoned buyer, for sure...I've been on the bay for well over 10 years, and am in the 1,700's...
