You forgot to add that, regardless, whatever you are prepared to pay, you should “snipe”, because if you lodge you maximum bid early, a shiller can apparently push you up until they outbid you and then withdraw their last bid (with some ridiculous excuse) so that you are again the highest bidder but you pay the highest amount you were prepared to pay regardless of whether or not there was another genuine bidder.
Not a bad trick, eh?
Certainly, “nibble” bidding is now only for shill bidders and naive fools.
