They already do that, just not as frequently. They change price tags of items every day by hand

In Poland it's already there in stores owned by the German Schwarz-Gruppe - Lidl and Kaufland. One might want to start shopping local to get exposed to 100% free range organic greed instead of lab-optimized greed at big stores.
Let’s call it what it is: price discrimination.
A problem area is pricing that changes 10 minutes after you put it in basket but before checkout. Though OP did go through some other abuse scenarios, though some were far fetched. This can't allow a store to personalize prices the way a web site can.
This is what I came to the comments to gripe about this whole thing. Yes, they can play some games and probably will, but consider: People will be watching. They do this and you bet people will track this crap and post about it. The blowback will be huge.
If they're stupid enough to try this, it will not last. lol. You can raise prices over the long term, but fuck around with short term prices people can see changing for no good reason? Yeah.....
And on the "personal pricing" - that's written by someone that doesn't understand how barcodes work.
But I'm sure they will try to play some games with it.
My grocery store has had these for a while. Dynamic price reductions are coming too. Instead of a set % off, it’ll calculate the most optimal percentage to take off based on popularity of the product, how long until expiry, etc. Just a heads up.
Thank you for telling the useful side of what this could be like. I'm on a sales team who considers options like dynamic pricing, and it is nice to know what good vs bad to look out for.
Looks like e-ink. A thumb tack taped to your thumb should take care of these pretty quick and inconspicuously. Especially if people generally agree this is stupid and should be shunned.
… you know they have cameras?
Do you have 0 slight of hand? Just buff your agility, youll be okay.
already here. just ask the inflation (not an american)
It definitely wasn't QE.
thats the joke. that inflation is dymanic we already have it.
I've gotta wonder... How expensive are these little networked e-ink displays? Probably not super expensive, but they've gotta be more than a paper price tag. Definitely more of a hassle to replace when someone breaks them by running into them, accidentally snapping them off, etc...
But more expensive than the wage of the person to go around replacing them for weekly sales? Walking back and forth to make a new tag to fill in an empty spot when something runs out?
Paper tags arent as easily damaged.
I’m still not clear on exactly what triggers this. Is it phone location, because a phone number is linked to all your data (unless you’ve been gaming it for the last 5-10yrs)? Do I walk by with my phone and the price goes up?
Is it like goodwill? Does the price change as you’re checking out? Do I grab a 2lb bag of medium roast coffee beans for $13, and because buying it consistently for decades, it’s now $18 at checkout? But is still $13 for the guy behind me who decided to try whole bean over pre-ground?
If rich people turn off their phones before hitting the parking lot and poor people leave theirs on, does the entire store get cheaper?
If you take a pic with your phone of the “advertised” price does that mitigate sudden increases while checking out, if you’re even watching?
Does having your unemployed, deadbeat uncle or kid do the shopping from their phone make it cheaper for the household?
What are the triggers?
OP was making a lot of shit up.
It doesn’t even have to be per person. It can just be by time of day.
We've had them for quite some time. They don't change price for individual customers, I don't think they change the price in the middle of the day either. But, I guess, they can change the prices just before opening, like if the wether service forecasts a rainy day they could rise the price of umbrellas and raincoats. Cold? Hot chocolate and soups. Hot? Ice cream and cold drinks. Certain asshole died overnight? Champaign and confetti cannons through the roof. And so on...
Oh, you mean price gouging
Oh, no no no. It's called "capitalism". Supply and demand pricing at it's finest! /s
They don't currently, but they could.
Take brand x on the shelf. Sold for $5 at a profit of $1. They sell 10 per week. You buy 2 if those every week, on Wednesday at about 6pm. Why not make them $5.50 next Wednesday and see what happens. Normal price on other days as no pattern identified.
Then once that's successful, why not have beacons detecting your phone, or even the stores app feeding your location. Then they can update just for the hours you are there.
Oh, but you'll say you swore it said $5 when you picked it off the shelf. The worker will say they have to charge what's there now and what it scanned as. Your choice to purchase it or go look for something else.
They've already started all this crap with online purchasing. It's just moving it to retail.
The industry calls this “clientelling”
That's the personalized prices. That's step two.
This one is the digital price tags that let the store manager or corporate office instantly raise prices throughout the store for everyone.
I can imagine price stickers would update daily, and individual users would get personalized discounts on their app.
App-less buyers would pay the baseline price in the sticker, app users would pay less. Like existing loyalty card programs, but with more data collection
It’s going to be hilarious when these get hacked
Reminder that by law, if the price is listed wrong:
Sometimes the price of an item in store or online at the checkout may not match the displayed or advertised price in store or online. If this happens, even by mistake, the business must either:
- sell the product for the lowest price - either the checkout price, or displayed or advertised price, or
- stop selling the item until the incorrect price is corrected.
What law? In what country?
Australia, the country the article is talking about. That was a quote from the ACCC website.
The closest thing I can think of would be Quebec, they have some fairly strong consumer protections, but i don't know how far they would extend in cases like this
stop selling the item until the incorrect price is corrected
Not a lawyer but couldn't they just refuse to sell it to you? We all know it would be bullshit but couldn't a company say "Oh that minimum wage clerk made a mistake, but don't blame them, just an honest mistake."
Or is the law, if it's on the shelf, it must be honored?
They would have to refuse to sell to anyone. It would likely not be lawful to leave it on the shelf and sell it at the higher price to someone else who might not have noticed the discrepancy, until they fix up the shelf pricing.
I will institute my own "dynamic pricing" scheme if this ever happens

If my local store switches to digital price tags to do this I'm just going to gather as many as I can and flush them down the toilet.
It's a nice thought but good luck not getting caught on the 3k cameras in the store and following you to your car.
It would be a shame if your phone was infected by a malware that rewrites all the prices in the tags in your vicinity.

My local Woolies has had e-ink tags for at least two years, maybe more. Between this and Coles hiring Palantir, we mostly shop at Aldi. Bunnings and Kmart using facial recognition as if it's no biggie as well. How long until they partner with CBA to check your credit card limit as you stand in front of the bananas to see how much you'll pay?

Boycott the stores that use them, it might help them change their mind behind they become the norm.
This is Australia and I think 90% of grocery shops are either this one or the competitor
