ah but what they can manipulate around you is the price, which is a behavior some places are trying to get ahead of

Has that actually happened in retail stores? All I can find on the topic is about online purchases (or ordering/paying online and picking it up at the store).

To do this in brick-and-mortar, you'd have to use remotely programmable price tags and detect who is looking at what, which seems doable, but then you still run into all kinds of tough questions with no good answers. 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? And did a legal sale even occur if I wasn't aware what I would be paying? I don't think it's going to work.

    • As of now, my local supermarkets still have price tags on the shelves. And if there's a higher price at the register when the item is scanned, they will honor the shelf price if you call it to their attention. The biggest supermarket now has e-ink shelf tags so I assume those are synced with their item database so that doesn't happen anymore.

  • Yes, it's happening in brick-and-mortar. They've been conditioning people to accept the idea that prices will differ depending on who is doing the buying through the use of apps and loyalty cards (https://web.archive.org/web/20201111164410/http://www.nytime...)

    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.

    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.

    • Somehow this doesn't scare me at all. Fast food restaurants have been doing this for like 8 years. Almost any order you could make normally, you could get a buck or two off of it if you order through their incredibly sluggish, bloated cross-platform-framework "app" and redeem a "deal." And they tell you this with giant ads.

      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.
