IMO it's just plain daft to enter a bid with more than a few seconds to go. There's just no sense in it.
The cool thing about a sniper is that it will do it in the last couple of seconds (always difficult manually) and while you're asleep, at work etc.Â
Interesting discussion, Tich.
I use snip.pl, btw. (Just in case you're looking around for a good service. )
