The last-ever penny will be minted today in Philadelphia

I'd say screw it, get rid of nickles and dimes as well. Quarters can stay, for now.

It's a complete waste of money and time continuing to mint such low-value currency. It can't be used for just about anything.

Unfortunately, I do see the problem with part of this. For a handful of items where it does matter, it will force people to use cards more if they want to avoid rounding. And the card providers already have a choke-hold on retailers, and the whole thing is basically a scheme that funnels money from the poor to the wealthy via interest and fees on the consumer, interchange fees, and rewards programs.

I know you're referencing more than pennies, but to speak to pennies, I find the current rounding noise in the US to be weird. Likely, it's just more of the media, talking heads, and youtube personalities trying to turn a nothing into something, story.

Back when we did it in Canada, I don't recall a single person I knew concerned about penny rounding. Everyone was sick of pennies. No one cared. Everyone was happy. And the math seems fair enough:

Basically, if something is $1.01 or $1.02, you round down. If it's $1.03 or $1.04, you round up. Rounding is to be applied after all taxes are paid, etc.

Of course, there was also central guidance and, well, everyone just followed it. It's called "having a society".

People blathering on about stores fixing the rounding are morons, there's no way to do so if you buy more than one item. No one gets ripped off with the above method. In the end, it just works out.

And really, who cares?! It's a penny.

> Basically, if something is $1.01 or $1.02, you round down. If it's $1.03 or $1.04, you round up.

So everything's going to be $1.03 or $1.04. Not sure why you think retailers (or any sellers) would ever, ever, ever let this play into customers' advantage.

But apparently pointing out that obvious truth makes me a "moron," because you can think of some clever ways to get around it that retailers surely won't work around.

If you buy two things at $1.03 or $1.04, it's $2.06 or $2.07 and rounds down to $2.05 more often than it's $2.08 and rounds up to $2.10. That's not "some clever ways." That's so basic it's absurd. They don't know how many things you're going to buy. They don't know how many things anyone is going to buy. There's no way to game the entire system for every combination of things people might buy.

Never mind this: When was the last time you bought something in person, in cash, and bought only one thing? Just think it through for a second.

> Never mind this: When was the last time you bought something in person, in cash, and bought only one thing? Just think it through for a second.

"In cash" is entirely separate from the rounding debate and is just the "people use cards, anyway" argument. It's not relevant to this discussion. This discussion is about cash. I do buy single items at stores sometimes.

Where's the law preventing stores from imposing an accounting fee for multi-item purchases, conveniently totaling a few cents?

Where’s the law preventing someone from doing this right now? I don’t think this cynicism is justified.

Similarly, if places are willing to price stuff at $1.03 for the few extra cents they’ll collect some of the time, then they can just raise prices on 99c items right now to $1 to collect the extra cent, which they don’t do because such prices have a psychological effect on the consumer that outweighs the small gain.

You don't think businesses take advantage of situations for more profit?

Take this year's tariffs as an example. As you may've heard, UPS is charging customs brokerage fees of dozens or hundreds of dollars on top of the actual tariff payment; identical shipments sent via FedEx or DHL are only charged a few dollars for the service of customs brokerage, so we know UPS's actual costs for providing that service aren't that high. They saw a situation where consumers would be confused about prices and took advantage of it to make a lot more money by simply charging a lot more than they need to.

"But where's the law saying they couldn't have just raised their prices by hundreds of dollars without tariffs? Where's the law?!" There wasn't one, they could've raised their prices for international shipments before the tariffs happened. But consumers would have noticed a lot more and accepted it a lot less. They took advantage of the situation because the situation allowed them to get away with it.

I'm not sure what you're arguing here. You admitted the $0.99 number has a psychological effect that outweighs the $0.01 gain of charging the extra cent. That would be the reason they don't do that. It's not super relevant to the discussion of whether rounding can/will be gamed.
