That's sensible bidding there Ian, something some of us should observe sometimes
Snipe can mean sitting there and clicking a few seconds before the auction ends, but can also refer to sniping as in placing a bid through a third party site which will bid through your account on your behalf, at a designated time. This is why sometimes even when you snipe with a second to go you still get beaten, the auto snipes can bid it within milliseconds of the auction ending. If you already knew that, I've read your post wrong and I'm sorry
