This how Trade Me (NZ auction site) works: any bid in the last 2 minutes delays the close time to 2 minutes after the bid. That can happen repeatedly, and I've seen it go on for over 20 minutes on highly contended auctions. It works well.

For the auction house that is

For the seller.

So scraping bots and “buy for me” bots are bad, but the incredibly annoying sniping bots are OK? That sure feels like a double standard.

I never understood why eBay set things up to enable sniping. Many years ago, there was an auction site called uBid. They had the sane rule: Bidding is open as long as there have been bids in the past 5 minutes. So the end date could be January 24th, 3pm, but if someone bids at 2:58pm, the deadline is extended to 3:05pm. And it keeps going. You know, like how auctions in the real world work.

This is how Yahoo! Japan Auctions works. If an auction receives a bid in the last few minutes, it is automatically extended.

It works quite well!

The act of bidding itself shows interest and raises the price.

Auto bid raises the price to the second highest price among auto bidders, basically running an instant second-price auction. Sniping avoids running these pre-close auctions.

It does not. Even if you submit a snipe bid the normal eBay bidding rules apply.

Establishing the price ceiling is difficult, though. You might arbitrarily set it as $23, but be sniped at $23.30. The sniper bot only needs to bid that small increment over your arbitrary ceiling. Can you really say that $23 was your hard limit, or would you have paid $23.40? Unless you're buying something also available at retail, nobody can be that accurate in foresight. Sniping removes the 'contemplation window'…

Then just put your actual hard limit in as your bid, and sleep soundly, knowing that if someone pays $0.01 more, it's OK because you wouldn't have wanted to pay that anyway. I've never really been bothered by "sniping" in eBay. I always bid my absolute 100% maximum, and if someone bids more than me, then they can have it.

But I want to get the item as cheaply as possible, not pay as close to my maximum without going over.

I've bought hundreds of things on ebay over the years and I've never understood the issue with "sniping". Sure, I've been outbid at the last moment. Losing an auction is always a little frustrating. But if I was willing to pay that price I should have bid it myself. Feels fair enough?

And I prefer to use sniping bots because they let me revise my bid all the way up until the auction ends. If I put a bid on something and then sleep on it and decide I don’t actually want to pay that much, I can lower my bid or cancel it. If I bid with eBay directly then I loose that flexibility. It has nothing to do with trying to outsmart people or be sneaky.

There are 9 time zones in the US and depending on what your buying in the eu, jp, etc, I'm not going to be up to deal with the end of an auction, either too early too late or you know I have a real efing job and i'm doing something. Having ends of auction require you to be around means you lock out large parts of the market.

I run up the prices in less competitive auctions just for fun occasionally, especially if I think someone is getting too good a deal.

I mean, dick move, but that has nothing to do with sniping. You could do that at any point during the auction and it would have the same effect.

Sniping means that bidders may have decided to put in a higher ceiling in order to avoid losing at the last second.

If there was never a worry about this, they could bring out (and decide) that ceiling only after being outbid.

That's exactly what automatic bidding does - it only outbids enough to beat the competing bid (up to your max) without paying any more than is needed. https://www.ebay.com/help/buying/bidding/automatic-bidding?i... (Manual bids have bid increments as well. Although others have pointed out that advance bidding might cause others to bid more than they would if they thought no one else wants the item. )

Not everyone is in auctions for the game, some people want to actually get the item. Though I imagine there's less and less of them, as most figured out long ago that auctions are a stupid waste of time.

In fact, I'm somewhat angry at sellers setting up auctions if there's no other way to acquire a specific item. Why they won't put a minimum price they're happy to part with some items for, instead of wasting time of a lot of people by withholding target price and pretending they're earning premium through work?

Yes, what I think happens is the following: User A's price ceiling is $10, User B's $12. When both reveal their max price early, the item will go to $10.50 ($0.50 increment over A's max price). User A then has plenty of time to notice the item being valued at $10.50 by someone. In many cases users then adjust the value they assign to the item and increase their bid. The result: User B has to pay more than $10.50 they would have paid when sniping the item seconds before auction expiration.
