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?
Au contraire
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...
surge pricing is what you are referring to which is pretty much the main form of dynamic pricing.
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.
Surge pricing really only works when you put the customer in isolation. Uber can do it because you're the only one seeing the rate for the trip you want to take. Amazon can do it because you're shopping while taking a shit at work. Nobody else sees the prices in your online shopping cart, that's not the case in retail.
The profit motive behind these tags is wage savings. It saves in the time it takes to change out price tags when the prices do change. It saves in the time used in finding and replacing missing or damaged tags. It saves in the amount of manual price corrections at the till when the tag doesn't match the till because the tag wasn't updated - or the lost time and revenue if someone abandons their cart because of said disagreement.
Could they do what you're saying? Technologically speaking, it's been possible for several years - we've had these tags on most major store shelves in Canada for a very long time now and apps tracking our every move. Why hasn't it happened already? These stores have had everything they need to implement this scheme, and of all the shady cunts in this world, Galen Weston would have by now if it could have turned a profit.
It's easier to just price-fix the bread and pay a fraction of your profit in lawsuit settlements decades later than to do what you're describing.
I a shop with 10 products, yes, I'd agree. In a supermarket with thousands of products, they can predict what you're likely to buy if you're a regular customer and you might be the only one buying those items that day.
I don't expect them to do it overnight. First they roll them out for the cost savings. Just like they did with barcodes rather than price labels. Then they start to look at other savings or profit centres.
After a while it becomes, why wouldn't they do it?
Why go through the trouble of gaslighting someone with digital price tags somehow changing the price on the fly based on whoever happens to be looking at it (BTW, what happens if two people with different price profiles are looking at the tag at the same time?), when they could just remove the tags entirely or even more likely, just close the store and force you to shop online where they can do all the usual online price fuckery?
Some countries require pricing to be visible. I would assume, just like online, they will use algorithms and ai to figure out what price point gives the most profit. Its only trouble to set up. The corporate world doesn't look at trouble. They look at cost. If the return investment is positive, they do it. If it's high, they do it as a priority.
Not all retail is online. Much is but not all. Groceries is one that is often better in person for that evenings meal on the way home from work. It's led to the rise of metro style supermarkets near transport hubs.
Grocery is already going online, look at all the companies sponsoring youtube vids. The margins for what you're describing are, at the absolute best, razor-thin.
E-tags draw significantly more profit from things like one-day (loss leader) flash sales, or in-store specials, or other conventional retail pricing tactics.
Take a 4-hour sale on some popular product, put an ad up on Instagram to get people in your store on the way home from work and you make a mint. You don't need E-tags to do that, but it means that you don't have to pay someone to change out the paper tags on that product twice in their shift.
You're getting distracted by the least likely way they'll fuck you over, when they're just sticking to tried-and-true collusion.
The industry calls this “clientelling”
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.
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
