If I buy a lot of Scott toilet tissue, I'm happy to get a discount on Scott toilet tissue.
Though mostly, the discounts I use are already posted on the shelf, I just need to "clip" an e-coupon in the app to get it.
They do send me emails and even postal mails with coupons too, but those all go in the trash.
I never get coupons for what I actually buy, I only get coupons for things I don't buy. Those things are sometimes related, but if I wanted the other brand, I'd already be buying the other brand.
The local supermarket chain near me has more or less done away with normal low prices on the shelves. If you want anything resembling a deal, you get to deal with their shit-tier quality app plus other friction inducting time wasting crap like "clipping" digital coupons. Plus opting in to all the associated tracking the app does in order to use it.
They effective raised prices 10-20% for the entire store and then the only way to get a deal is use the app. This is only currently slight hyperbole - every month it rolls out more and more in this direction.
This way they can tell regulators "we only give discounts in a discriminatory manner! We don't raise prices!" when the time comes.
With any luck a judge will see right through that unmitigated bullshit, but I'm not going to hold my breath.
I refused to get their card and stopped shopping there.
Don't expect discounts on what you buy often. They know they have you hooked on those already and they'll drive up the price on those items (for you) the minute they can. They'll give discounts on brands you don't buy to entice you to switch (if those other brands pay them enough to do it). These surveillance pricing systems are not for your benefit. They aren't there to save you money. They only exist to take more of your money away from you.
They've known for a long time now that their profits will go through the roof if they can get away with it, but the fact that consumers find the practice offensive has held them back along with the cost of initial investments in things like digital price tags and facial recognition systems (https://link.springer.com/content/pdf/10.1057/s41272-019-002...) but all of it is coming. The big chains have already started. By the end of this year Walmart should have digital price tags in every store. Facial recognition is spreading too (often using loss prevention as an excuse). The grocery chain Kroger announced they'll be using facial recognition to offer different prices to different people. Their digital price tags scan faces, and your track appearance and behaviors, like how long you spend looking at various products.
It'll be simple for stores to do things like charge people more when their cameras see them wearing expensive clothes, or when the data collected from their app shows that they live in rich neighborhoods or when they can use the data they collect on you in combination with information from data brokers to learn what your income level is. I fully expect things to get even weirder like stores setting higher prices for people with the wrong opinions or political views. Algorithms will be caught "accidentally" discriminating on things like skin color and gender.
There's a little bit of pushing back against that kind of things in some places, but with the massive amounts of money on the table I expect that politicians will be bribed to allow it.
> If I happen to see the price tag change from $3.49 (perhaps set for the person in front of me) to $4.49 and I put that item in my cart, which price am I getting charged at the register?
The store shelves have cameras in them. You won't see your price until the system detects you. They can even display your photo/avatar next to the price so you know that it's for you. Facial ID at the register tells them who you are when it's time to pay up. That's just for now though. Eventually it'll likely all happen in a cell phone app and you won't be able to as easily look over someone else's shoulder to see what price they're paying.
The function is to get incremental sales (and hopefully establish a pattern of repeat business) by discounting selectively to people who might not buy at all otherwise.
If you're thinking "But they should give that discount to everybody!" that's not a thing. There's not enough margin in the first place, especially at a supermarket or Walmart, that everyone could just have lower prices on everything.
My grocery store already sends me individualized paper coupons every month.
All of this is promotions. It's all just trying to get some incremental sales, and hoping that if you get an offer for free hot dog buns you'll also buy the hotdogs.
Some particularly skeevy car dealers were skewered many years ago for saying "Advertised price is less tax, title, and additional $2,000".
But they CAN get away with saying "The $8.99 burger is $11.99 unless you: - possess one of a range of sanctioned devices - have access to data services - are able to create and manage an account - are willing to opt in to whatever tracking/marketing gimmickry - can claim the "deal" in advance
Each of those steps is a funnel that opts out at least some potential customers from the deal. The 12-year-old who doesn't own a phone can't get the deal. The 85-year-old who can't operate Android can't. The person making impulse purchases and not pre-researching their meal selection misses the offer.
I feel like there's a argument for a precedent akin to "no purchase necessary to enter" for sweepstakes-- no additional purchase, software install, or commitment should be required to claim any advertised offer.
Strange how this totally worked until a few years ago. I never cut coupons or any other time wasting shenanigans, but was able to stop up on deals on the commonly used shelf-stable items I buy without even needing to signup to a loyalty program.
I understand price segmentation is a thing. But it's gotten pretty exhausting and only increasingly so.
Fast food you can simply opt out of. My health improved due to them shifting all the "deals" to the app, and doubling menu prices. Groceries are a different thing.
This isn't even a little hypothetical- bluetooth had to anonomyze the MAC address to stop this, and it still fails sometimes.

I also think this hypothetical "scan to see your price" scenario is a lot worse. As things stand now, there's still a baseline price. If the shelf says $8.99 then you know that you may be able to get a better price through their loyalty program or with a coupon, but it will never be more than $8.99. In a fully dynamic pricing world where you have to scan scan to get a number at all, which is what a lot of businesses would really love to have, you'd lose that baseline. That item might ring up at $20 if the system decides I'm desperate or inattentive or just don't care. This is already possible online, of course. If it spreads to grocery stores, though, I'm going to start channelling Ned Ludd and it won't be pretty.
