eBay and Craigslist finds

if you think about it, having a higher bid already typed in the window, all you need to do is click the mouse - you can do that even within 1 second

In my experience, biding in the last 10 sec is very tricky. Ebay seems to react very slow or not at all in the last secs. I place my final bid approx 20 sec before ending. Otherwise I risk that my bid isn't processed anymore. Waiting till the last 4 secs is too much of a risk imho.
