A recent auction result:

ebart3 (0)
       Last bid at:       $50.01
       Date of bid:       10/05/99, 17:52:29 PDT

pmfoster (10)
       Last bid at:       $50.00
       Date of bid:       09/30/99, 15:31:52 PDT

At this price level the bump is a buck. There is NO WAY ebart3 should
have gotten this item for one cent more, he should have had to go to 51.

Now I am no fan of Ebay but here is one possible scenario as to how this could
have happened...

1.  Opening bid on box of 20 widgets = $30
2.  On 9/30 pmfoster bids $50 but because of proxy bidding price is set at $30.
3.  On 10/5 ebart3 comes in and sees a $30 bid with a minimum bid of $31 and
places a maximum bid of $50.01.
4.  Proxy bidding occurs and because ebart3 has out bid pmfoster by $.01 their
bid stands.

In this scenario ebart3 is not bidding $50.01 on something that is allready at
$50.  They are bidding on something who's highest bid was $30 with a minimum
bid of $31.

I hope this makes sense.  If it does not let me know where my logic is off.

(...) That is how eBay does it, I believe. However, Larry (among others, myself included) feels that you should be required to exceed the proxy by the minimum bid, not just the current bid.
