PaulThis is how I think it works: if you are the high bidder on a lot, but your high bid is an odd amount, and then you bid again, ebay raises your bid to the next regular increment.
For example, let's say you haven't bid yet. The current high bid is displayed as $12.00, but the high bidder's maximum bid is $15.11. You then place a bid of $15.15. You are now the high bidder at $15.15. Now, $15.15 is not a normal increment. The next normal increment after $15.00 is probably $15.50 or $16.00. But since your maximum bid was only $15.15, ebay can't charge you more than $15.15, and it lists your high bid as $15.15.
But, let's say that you then raise your own bid by placing a new bid of $20.00. Ebay will automatically raise the displayed high bid to the next normal increment ($15.50 or $16.00). In essence, ebay is erasing your $15.15 bid and replacing it with your $20.00 bid.
