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.
I don't understand this line of reasoning. I don't do auctions, but if I did, it would be because I want that item. When I want something, I never have an absolute hard price ceiling; if I'm willing to pay $10000, I'm willing to pay $10000.01. I can't imagine anyone who would be happy to pay $X for an item but not $X + $0.01.
Like, if I'm at a store and an item costs $500, and I bring it to the checkout and the cashier says "oh sorry that was mislabeled, it's $500.01 not $500", there is no world in which I go "okay never mind then, $500 was my max". There does not exist a situation where I've decided I want something at price $X, but would not buy it at price $X + $0.01, because $0.01 is absolutely negligible.
So where does this fantasy of an absolute max price come from?
It's not supposed to be some red line absolute max price, but rather "how much is this item worth to you?" You set that as your max bid price. If you get it at auction for less than that, you got a good deal, but if you buy it for more, you got a bad deal. If someone outbids you, then maybe it was worth it to them, but you (supposedly) would not have wanted to buy the item for that much, and would rather use your money for something else.
For tricky-to-price items like unique art pieces, the idea that you can pin this down might be a fantasy, but for commodity items it's pretty reasonable. If you can buy the same thing at costco dot com for $500, then it's probably not worth more than $500 to you, and if at auction you get outbid and it sells for $500.01 then you'll shrug and go order the same thing for a cent less, having wasted only a few minutes of your time. If the item you're bidding on is discontinued (e.g. it's last year's model) but you can buy a slightly better one for $550, and you can spare that extra $50, then again you won't be too sad about getting outbid. Online auctions are more popular for used items, but again in that case you usually still have an idea of what a used item is worth to you.
The logic of "you shouldn't ever need to snipe, just bid your max price" only works if we assume that the max price is a red line though. If I "value something" at $5000 (as in I want to buy it at $5000), and I bid $5000, and someone bids $5000.01, I would probably be happy if I sniped them and got the item for $5000.02.

Your max price should be the price such that you're indifferent between buying the item at that price and not buying it at all.
At a shop, usually you're paying less than the maximum you'd be willing to pay, because the shop's prices are fixed and it would be a big coincidence if the price they set happened to match your max price exactly.[1] So even if we model you as homo economicus, it's normal that you're almost always fine with paying $X + $0.01.
In the case where $X really is your max price (i.e. it's right at your threshold of indifference), the idea of rejecting $X + $0.01 seems less silly. You were already very close to deciding $X was too much, so you're probably feeling ambivalent about making the purchase, and the trivial nudge of an extra cent being added to the price might as well be what pushes you over the edge.
[1] There are exceptions, e.g. when you have a negligible preference between brands A and B, so you're defaulting to brand A because the prices are exactly the same, but you would buy B if it were marginally cheaper. But that doesn't affect the main point here.
I don't see why I would buy something if I'm indifferent to whether I buy the thing.

it's because this argument of "what is $0.01 more?" can be extended forever, implying you are willing to pay an infinite amount of money for anything. since we know this is silly, we try to understand what our "real" maximum is. this is difficult to do for exactly the reasons you mention in your comment! surely $0.01 is negligible! there is a tension here.
and so, absolute max price is not a fantasy - the world would be absurd if it were - but instead its a real and difficult to construct value

It can be extended forever in theory, and sure, that is an interesting philosophical discussion, but it isn't in practice. We're discussing sniping. That means you make the choice once: do I send in a last-second bid that's $.01 more than my "max price", or do I not?
The field of Economics
But I want to get the item as cheaply as possible, not pay as close to my maximum without going over.
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. )
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.
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?
But if that someone isn't rational it is better to not give him the time to react to your highest bid.
Also some sellers seem to use some fake accounts to bid high on their own item, revealing your max bid, then cancel their bid, then bid right under your max bid to maximise their sell price. Happened to me twice, and now no longer setting my max bid in advance since.
I thought eBay doesn't allow you to cancel a bid you placed.
It does. You can argue you bid a wrong amount by mistake. It's necessary because mistakes do happen, and it even happened to me to retract a mistake once (was bidding on two items simultaneously in two tabs and mixed them up). But it gets abused.
What were you buying?
Mostly electronics, SSDs, motherboards, etc.
It gets into the nature of "Which grain of sand makes it a pile?"
Knowing people bid snipe by bidding one cent over whole dollars, would you consistently bid two cents over if it meant you would win more of your auctions?
One cent is negligible. If you asked me if I would have paid $10.01 instead of $10.00, I'd probably say "Sure". $10.02? $10.03? Like, where does the line get drawn?
And then you come at it from the other way. Let's say I'd pay $10, but not $11. But what about $10.50? $10.25? Or we can go down by pennies again.
I agree, put in your limit and walk away. If you get overbid, even by a cent, don't sweat it. That's the game. But I can see why people get frustrated when they lose an auction by one cent.
Maybe eBay should publish the price the winning bidder actually bid.
This would let people stop thinking "I lost by one cent" in that situation. It also has a marketing benefit: look at all these people who got great bargains relative to what they would have paid. And it's not an unreasonable amount of transparency: in second price auctions e.g. for stamps or electricity, it's normal to publish the details of all the bids.
Of course eBay has already thought about this more deeply than me and perhaps trialled it and decided they didn't like it. Maybe it's off-putting to sellers to see they lost something for $10 to a buyer who would have paid $30?
The only way to win by a cent is to put your bid at that.
If the current price is $5 and your max bid is $30 and I put a max bid of $100, it will make the current price $31 - $35, whatever the increment is.
To get ebay to accept a bid of one cent over, you have to explicitly set that. Let's say, I'd actually pay $30 as well. $30.01 isn't materially different. So if I put in $30.01, my bid becomes higher than yours.
If you enter your maximum bid in ebay you're revealing it. With sniping no one can discover your maximum bid.
The 'nibblers' will invariably show up and bid small amounts until they exceed your maximum bid, while not revealing theirs.
It's a second price auction. Who cares what their limit is. If it's more than the value of the item to you then they will win. Otherwise you will win.
Exactly. I could put $100,000 as my max bid, but if second place only bids $10, then all they know is I bid $11 (or whatever the increment is). eBay doesn't tell anyone my max is $100K.
