>Bidding Fun -
As of 9:30 am PDT, the high bidder was Walt at $360, and his 'ceiling' was set at $368. At 9:38:08, the ultimate winner, cotti, places a bid with a ceiling at or over $665.98, and becomes the high bidder at $373 ($5 over Walt, just enough to lead). 6 seconds later, efisher bids $655.98, and eBay applies cotti's ceiling, and the new high bid is cotti at $665.98 ($10 increments kick in at $500, I think). Efisher got the 'you've been outbid' message, but since he sniped at 4 seconds remaining, it was too late for him to increase his bid. Cotti was leading before and after efisher - all efisher did was to cost cotti almost $300!
Now, all this assumes one unlikely fact - that there weren't any others who dropped in bids between $360 and $655.98 in the last few seconds, only to get the 'invalid bid amount' response, because at 9:38:14 it was already over $665.
But, this auction can be used to show the value of sniping. Eliminate cotti and efisher and other unknown bidders, and assume that Walt (brasscity) and bikerbeaner were the two highest interested bidders. And, assume that no matter what, Walt is not willing to pay over $368, and bikerbeaner will only go to $355. Bikerbeaner placed his bid at 4 am EDT, with ceiling at $355, and he was then the high bidder at $275. Walt comes in a few hours later and bids it up in 8 increments, with his first bid at the minimum increment - $280 - at 8:38, and his last at $368 at 9:29 - he became the leading bidder with his 6th bid of $360, then he'd bumped that up to $368 in two more increments, for a bit of breathing room.
But, assume bikerbeaner had sniped instead - Walt would have become the leading bidder immediately upon placing his first $280 bid at 8:38. Seems we can safely assume that Walt would not have then placed his next bid with his 'real' $368 ceiling, since he didn't do so in actuality. Auction approaches closing, Walt remains high bidder at $280 - maybe he has even put in an extra bid with ceiling at $290 for breathing room (just like he actually did from $360 to $368).
Assume bikerbeaner places his one and only bid at the last moment - for $355 - and even though Walt was ultimately willing to go higher, the item would go to bb - for $310! But, by not waiting, he loses it to Walt instead, at $360.
Look at it another way - even if bikerbeaner was willing to go $400, and thus he was gonna take it from Walt no matter what, he likely would've saved almost $100 by sniping. Again assuming Walt's absolute ceiling was $368, by giving Walt his own earlier bid to 'shoot at,' bikerbeaner would've eventually paid $5 over Walt's last bid, i.e. $373, whereas by waiting and sniping, he could've won it for $5 over wherever Walt stopped once he became high bidder - likely somewhere between $285 and $295. Either way he wins it, but by sniping he likely wins it for a whole lot less.
As long as you truly bid every dollar you're willing to spend, it is ALWAYS to your benefit as a buyer to snipe. Many, many times I've sniped in a bid that was 3 or 4 times what I ended up winning the item for - because you never know what OTHER snipers are out there! Nonetheless, it's always a pleasure to bid $200 for something, then win it for $50 or $60.
It's human nature that it's hard to know quite what you'd pay for something until it gets bumped up inch by inch. But, bidding items up incrementally, as Walt did here, only tips off snipers like me that your ceiling is probably not much over what was necessary to become the current high bidder - and even if you do put in a 'breathing room' bid after becoming the high bidder, that shows and tells other bidders something too. I've also looked at the bid histories of the other items bid on by my 'competition' for a particular item, to see what bid patterns I can see - size of 'breathing room' bids, likelihood of another last-minute bid, etc.
Walt, I've probably learned as much from your posts as I have from almost anyone here, and I have immense respect for your tool knowledge, so I hope you understand that I'm offering this only to illustrate - and selfishly, myself I hope you will keep on bidding just the way you do now!
