All Good Explanation's. It took me awhile to figure this out myself, as I was afraid I was going to over bid, until I finally took a shot at it. I will just add, that I too always wait to the last few seconds to adjust my high bid number, BUT, if you have a slow internet connection (such as dial-up), you may not get it in in the last 5 seconds. Remember, it asks you to bid, then it asks you to confirm your bid.
