Forget Milk and Eggs: Supermarkets Are Having a Fire Sale on Data About You (themarkup.org) 104

When you use supermarket discount cards, you are sharing much more than what is in your cart. From a report: When you hit the checkout line at your local supermarket and give the cashier your phone number or loyalty card, you are handing over a valuable treasure trove of data that may not be limited to the items in your shopping cart. Many grocers systematically infer information about you from your purchases and "enrich" the personal information you provide with additional data from third-party brokers, potentially including your race, ethnicity, age, finances, employment, and online activities.

Some of them even track your precise movements in stores. They then analyze all this data about you and sell it to consumer brands eager to use it to precisely target you with advertising and otherwise improve their sales efforts. Leveraging customer data this way has become a crucial growth area for top supermarket chain Kroger and other retailers over the past few years, offering much higher margins than milk and eggs. And Kroger may be about to get millions of households bigger. In October 2022, Kroger and another top supermarket chain, Albertsons, announced plans for a $24.6 billion merger that would combine the top two supermarket chains in the U.S., creating stiff competition for Walmart, the overall top seller of groceries.

U.S. regulators and members of Congress are scrutinizing the deal, including by examining its potential to erode privacy: Kroger has carefully grown two "alternative profit business" units that monetize customer information, expected by Kroger to yield more than $1 billion in "profits opportunity." Folding Albertsons into Kroger will potentially add tens of millions of additional households to this data pool, netting half the households in America as customers. While Kroger is certainly not the only large retailer collecting and monetizing shopper data through the use of loyalty programs, the company's evolution from a traditional grocery business to a digitally sophisticated retailer with its own data science unit sets it apart from its larger competitors like Walmart, which also collects, analyzes and monetizes shopper data for brands and for targeted advertising on its own retail ad network.

    I was a mere child in the 80's - 90's when our local supermarket started the discount card program and even then myself and my parent's knew they were doing to track what people were buying. It's obvious on it's face. This one is an old school data collection scheme, one of the OG systems.

    Of course this is kinda how it's supposed to be in a fucked up sortof way? You can opt out of it pretty easily, just don't use the card and pay cash. If you want those sweet sweet deals then tht's kinda the tradeoff (or get old school clipping). Or shop at a store that doesn't have a discount card program (Publix and Aldi don't to my knowledge)

    • Hmm...I've not seen "customer cards" in a long time at any grocery stores where I live.

      I was recently visiting parents and did see they had those cards at Krogers.

      But where else do they actually have these?

      The only store around here that I've seen use them is Walgreens....

      And..does anyone play the game I used to play with them when I would sign up (multiple times)...put in goofy names to fsck with their databases?

      • I get a new card every time I come in. Not to fuck with their data collection, but just to be a vengeful asshole.

        If they want to make me have some stupid card to get the price so prominently displayed in the shelf, I'll happily hold up the line while they issue me a new card with fake customer info....every fucking time I come in.

          Here's the thing that pisses me off about loyalty cards: they're a scam and a shell game, and the suckers are lining up to be fleeced. There's no such thing as a true discount in these scenarios - companies just jack up the price to make whatever profit they deem fit, then jack it up again to pay for the costs of administering the loyalty program.

          Cardholders pay a price that, although it's "discounted", is higher than what they would have paid if no loyalty program existed. And people like me, who refuse to

      • But where else do they actually have these?

        Winn-Dixie still does 'em, as do Walgreens and CVS. Usually if you don't have a loyalty card, they have one up at the register that they'll scan, so the privacy fears are generally a bit overblown.

        Zuck already knows everything about you anyway, so the privacy ship has sailed a long time ago. Might as well just save a few bucks on today's ever-increasing grocery bills.

        • Albertson's when it was around did them. Up in the northeast pretty sure Shoprite and Stop n' Shop have them. Back in "the day" when I worked at A&P and Waldbaums they both had them. By their very nature all the membership stores like Costco, Sam's Club and BJ's have them (it's baked into the system!)

          It was all the rage for supermarkets for a couple decades at least, I would say it's more recent development that a place does not have them.

          • They might though, because lowering prices is a way to get more people into the store so they can collect more data. It could even reach the point where the stores no longer make any money selling food, instead getting all their profits from data gathering; that's the business model for some streaming devices (Fire TV, Roku) and some TV sets (Vizio) are close to it.

        A common hack to get the discounts associated with the loyalty card without being tracked is to use 'your' phone number as an alternate ID. You'll find that in many cases someone has already registered: (your area code) 867-5309. (It works in several stores in my area)

        Very easy to remember for those of us of a certain age.

          • Or are you one of those lazy goitres who just ditches it wherever you feel?

            Bless their heart, though. I nearly filled up the change cup (more accurately, a cigarette tray, but I don't smoke) in my old car with quarters from Aldi, by returning someone else's cart at almost every visit. There's that old saying "a penny lost is a penny found". Well, due to inflation, it's now a quarter.

          Actually, every time I shop at Aldi I gain a quarter by using a cart someone abandoned, and then actually putting it back. Produce quality seems the same as every other store around here, so it probably depends on your local suppliers.

    • just don't use the card and pay cash.

      The second part, "pay cash", is the key. If you use your credit or debit card, you are tracked just as well as if you used the special card from your store. Depending on the store (like Walmart), you can track exactly what you bought and when.

          Nope - They get at least your first initial (but many issuers provide the entire first name) and the last four digits of the account. They still have you uniquely identified solidly enough they are going to easily be able to tie your records up with an external data partner and get the full info if they are even interested.

        Nah, if you want real anonymity, you pay only in tumbled cryptocurrency. Sure, your shopping options might be a bit limited, but no sacrifice - no privacy! When you're sitting at home eating your Ramen noodles that you probably overpaid for from some creepy dude on Craigslist, you can take comfort in the fact that Kroger has absolutely no idea who you are.

      It was best thing about Publix.
      Now I just see who is running the Pepsi product BOGO and shop there for the next two weeks. Winn-Dixie has been winning on that front more and more often. Helps that they send flyers still.
      • Do they now? They used to advertise specifically about not having any loyalty cards. Just a bit dissapointing if they've changed stances on that. I rarely shop there outside of the occasional sub because it's definitely more expensive than the other local options.

      Another OG data collection scheme was (is?) the warranty "registration" card. The vendor -- and it seems all did it -- didn't tell you the warranty was not contingent on registering.. but many people did send in the little card. Even as a child I read the questions and thought "WTF does Panasonic want to know how much money I make, what race I am, etc etc" -- it was all market research.

      They donate rather heavily to the Republican Party, which was why the Parkland kids (who are now all actually adults, my how time flies) staged a protest inside the store. It's just worth mentioning in case that doesn't mesh with your political views and you have other options for grocery shopping.

      While I like to say I'm personally avoiding Publix for reasons of practicing ethical capitalism, I mostly don't shop there because they're just damned overpriced on most goods and they do not price match. I like

      • Yeah I don't shop at Publix often mainly because they have just become significantly more expensive than the other local options for not a ton of benefit. Aldi has way better prices, Winn Dixie is fine when I need a wider "supermarket style" selection and the local hispanic markets honestly fill a lot of the specialty needs.

        I don't like Publix's politics, I do like the subs, the deli section is still better than the others and the fact that they do in fact pay and take care of their employees pretty decent

    • The difference is that when the cards first came out, the stores were only gathering data to use for themselves; to make better decisions about what merchandise to carry and promote, and possibly to send some personalized promotions your way. Selling the data to outsiders came later. Radio Shack was doing it even earlier, way back in the 70s when they asked for your phone number, but they didn't sell that data either or even call your phone number; the number was just used as a database key.

  • They have no loyalty card or similar means to identify individual customers. They could be tracking through credit card usage, but if you pay cash, they have no way to track you. (And their prices are actually the lowest of the 3 supermarkets in town, Hannaford and Shaws being the other two.)

    Make shit up. When I created my Kroger card long ago I used fake everything. Now I just enter that old fake phone number into the card scanner to get my "discount". Oh, another thing that works, tell the cashier to use the card located at the register. Every register has one and the person watching over the self-checkouts do too. If they refuse (which they won't), simply walk away. Kroger sucks because without using that stupid card prices are much higher for a lot of items.

        I'm not the OP, but I *do* pay cash. Where I live it's not uncommon for the merchant to charge about 1.5% for any transaction using a card. The banks are rich enough already without me giving them 1.5% of everything I spend. Strangely, I still see plenty of people paying by card (or tapping their watch). What cost of living crisis?

      • This is not about using credit or debit cards. This about using those "loyalty" cards to get goods at a cheaper price. I pay with cash most of the time too, but less cash with a poisoned loyalty card.

          The stores know some people lie on their card applications or otherwise try to evade the surveillance. They're looking for cards that have bogus information tied to them. They're still useful even without being tied to a real world identity, because they can still build up a profile of the person using the card. The moment you pay with a regular credit or debit card, though, they can tie that shopping profile to your financial information, and you are no longer pseudonymous.

    • The price difference for being or not being 'in the shoppers club' can be as high as 30% for some items at Kroger-owned supermarkets (They own several chains).

      That's a strong incentiviser for shoppers, and I can't imagine how Kroger makes THAT MUCH money off of your purchase information. I guess most people haven't heard of ad-blockers yet. . .

It attempts to price content as negligibly cheap but not free, which ignores the fact that there is a non-trivial cognitive cost to decide whether the very low price is worth the very low value. Studies consistently find that people dislike micropayment schemes.

      Most people are barely aware of what they are handing over. Go and ask people at the checkout store what they think they share when using their loyalty card. I'm quite sure at least half think at most what they bought. Some probably believe that certainly the store won't even share that, maybe just how much they spent or how often they shop. You'll likely find a few that aren't even aware that the store shares data at all.

    I remember a story about how Target's systems were so sophisticated that they were sending out coupons for baby products to a pregnant teen before her family (at least, it never was clear to me whether she knew at that point or not) knew she was pregnant.

    It's gotta be a story from at least 12 years ago because I had heard about it from my managers when I was working at Target, but the non-paywalled story [forbes.com] that I can find today comes from 2012 (actually, exactly 11 years ago looking at the date). It was to the point where the father called in to the local store, chewed the manager out for advertising such things to his daughter, saying they were encouraging her to get pregnant. A little while later, he learned that his daughter was already pregnant.

    • They’ve kept most of the details secret, for obvious reasons, but they did let on that one of their pregnancy markers was purchasing unscented lotion when you hadn’t before. Presumably, morning sickness makes women switch to unscented. You might think that demographic info would matter, but it doesn’t much here - if you’re buying for a pregnant woman, it doesn’t much matter if you are the pregnant one or not, they will sell you baby stuff.
    • I remember a story about how Target's systems were so sophisticated that they were sending out coupons for baby products to a pregnant teen before her family (at least, it never was clear to me whether she knew at that point or not) knew she was pregnant.

      It's gotta be a story from at least 12 years ago because I had heard about it from my managers when I was working at Target, but the non-paywalled story [forbes.com] that I can find today comes from 2012 (actually, exactly 11 years ago looking at the date). It was to the point where the father called in to the local store, chewed the manager out for advertising such things to his daughter, saying they were encouraging her to get pregnant. A little while later, he learned that his daughter was already pregnant.

      Yeah, the story is at least that old, but it reeks of confirmation bias and accessibility bias to me.

      How many random people got baby product ads, shrugged at how dumb it was (or went and yelled at a poor manager) and didn't go on to find out someone in the house was pregnant? And how many stories were written about them?

      To show that Target was actually able to correctly predict pregnancies and advertise to mothers-to-be, you'd have to show that they didn't also deliver those ads to non-pregnant women of

    Afterall, a broken VPN connection is giving doctors notice on what you buy...

  • Safeway has a two-tiered system. The older one uses your (alleged) home phone and a name you gave (or made up) when you registered. It gives substantial discounts.

    Add the new one on top of it and you have to give them your cellphone n.umber (and, I think {no WAY I'd sign up}) use an app at some points. That ties it to you (or at least a burner phone) and lets them track you around the store. This gives some deeper discounts - often 50% or even more, sometimes even free stuff - on significant amounts of g

      I think most people don't have problems with the grocery store using information to provide services, deals or even do marketing. The question is what happens when they sell it to a third party, and do they even vet those third parties. Anonymized data is one thing, but information such as detailed location tracking is quite sensitive. Imagine if someone has a restraining order protecting them and now the potential criminal can see their habitual movement patterns.

  • They want to sell me stuff I'm interested in?

    They want to give me ads for stuff I am interested in, rather than random shit I would never buy?

    Oh...the horror!

  • This is nothing new and because data is cheap to gather and store they'll look for every way to mine it as well. Shit, just browsing for a product on their website tags you for life.

    I still get "Because you bought this" or "We have recommendations" from Amazon.

    My favorites:

    "Because you bought The Magic School Bus Software" from like 1998, "We recommend Dora the Explorer"

    Now because I have grandkids the same thing is happening all over. Buy a Kindle for kids and you get all the ads and software sellers becau

  • they want to make *all* the money - Jim Stephanie Sterling.
  • I have an ancient Safeway card, from days of yore, or at least when they first got 'em. When I use it the checker looks at the screen or receipt and says "Thank you, mister..." and then trails off because the name field is completely blank. You can't create a Safeway card account like that, but nothing prevents one from existing, and they seem to have botched the transition of the old cards into the current database. When that happens I make sure to say "You can call me Mister Blank" or "You can just think

  • Can't they do this when you pay via credit card? (Which is why stores should not get your credit card number, or personal information when you use a chip & pin card - but I was under the impression that they still do.)

    • Can't they do this when you pay via credit card?

      Walmart certainly does. Their app shows past in-store purchases made using any credit card which you've associated with your account.

      I'd venture a guess that the reason certain stores have stuck with loyalty cards are that they enable tracking of cash purchases, and the cards themselves do create something of a feeling that you're participating in an exclusive membership, even though they hand them out to anyone simply for the asking.

        Now that you mention it, I do remember having this discussion with a store manager who said they they just wanted to get something with the store logo onto your key chain.

  • I got a coupon

      This. Who gives stores real info? Heck my local grocery store I never even gave info, as I can type in any random number and it works, as every one has given them a phone number. This works at most every store. The local pet store, random number. Why hand out real information? Would probably work at gas stations, but I don't want to be jerk and take someone's fuel points or something.
      • Use 555-1212, anyone who does isn’t worried about the reward discount. Just the basic 5c/gallon or whatever.
  • In the early 2000's, when every grocery chain suddenly wanted your telephone number so you could be a "club member", I started telling people that this was for data collection purposes – for profiling you – and not to go along with it. Almost every single person told me I was deluded.

    You see, phone numbers used to change every time you moved, but with cell phones and 'number portability' laws, people started keeping their phone numbers as a permanent number. Same thing with email addresses. Well

  • Simply running the same PAN (private account number) every time you check out (ie, paying with the same card) is enough to establish a cohort of data on your behavior. This sort of data tracking is hardly new - it's positively rampant within the general credit-card processing industry since at least 2010 (could be more, but that's my furthest recollection).

    So... I don't get the point of the outrage article... Pay with a thing that has a unique ID, and then think companies aren't going to track behavior of t

    • Exactly. This helps them pay for ads that are tailored for me which I will never see because I use ad blockers.

  • 15 or so years ago at the Chaos Communication Camp we had a discussion about these cards, which at that time had been around for only a few years. I suggested that people should just exchange cards with someone else from time to time. To mess up their algorithms. Some people did it right then and there. I still think it's a good idea.

    Since most cards require you to fill out a form only, and don't check anything, you can just fill out a new form at a different store of the same chain every quarter or so, wit

  • Then they are going to find out that I no longer go into supermarkets and haven't since they started offering to pick my stuff for me. Free labor, why wouldn't I use it?

  • Back in the day when my mother used to buy meat at the butcher, vegetables at the greengrocer, etc., these folks knew her personally. The good old days, right? Yeah, but they gossiped about the other customers. So, which is better? (Yes, I am old, and that really was the case in 1950s NYC. Imagine how much worse in a small town.)

  • Just type in someone else's phone number as the alternate ID, tracking problem solved. I know all kinds of phone numbers I can use.

  • If they're selling info about my shopping habits that slightly decreases the prices I pay for groceries. Since I see no ads ever, it costs me nothing. The people who are paying Kroger for my info are wasting every penny then spend. Yay.

  • Nobody reads or even asks for any 'privacy statements' when they sign up for things like 'discount club cards' so they have no idea what's being collected about them or what's being done with that information, and now after all this time someone finally notices? I'm laughing my ass off right now.

    Pay cash at the grocery store and forget the 'discount' cards. There, you just took back a little of your privacy, was that so hard?
