Recently I had two snipes in a row where I won the auction at exactly my bid, not a penny more, not a penny less. (GBP 3.68 and 3.67).
Given that bid increments at this level are GBP 0.20, I figure if someone has a bid at GBP 3.40, I'll win at GBP 3.60; or if the bid is GBP 3.50, I'll get the sniper message "bid under increment" (which has happened a few times).
So I think it's weird two times in a row I've won at my exact figure.
Any other explanation?
As I understand it the way it works is that if you snipe (say) Â£3.68 and the next second somebody snipes (say) Â£3.50, you win because you'd already registered a higher bid -- but as it's less than one bid step (20p) above their underbid, the amount registered is simply as near to "underbid + bid step" as it can get, hence the full Â£3.68.
And conversely if somebody snipes Â£3.50 and the next second you snipe Â£3.68, you get the "bid under increment" message and lose. So it doesn't always pay to snipe too
close to the end -- all you really need to do is to get close enough to stop people having time to react manually.
