Perhaps, but at least in my area, I can just choose to shop somewhere that doesn't require a club card to get discounts. Most places have a club card where you get points to redeem in the form of cash back after some amount of spend, but the minimum redemption is so high that you'd have to make them your main store to get enough to redeem, so I doubt most people with a card actually redeem the points. Advertised prices don't need a card, except at 1-2 places (e.g. a rebranded Kroger store in my area). I just avoid places that require a card to get advertised prices, and my life is simpler (no recitation of my phone number, just a "no thanks"). However, everywhere asks for my phone number, so I can't help but feel like people are being coerced into tracking. I think we need to remind friends and whatnot that giving your phone number out quite often doesn't save you money, and just remember a short list of places where it does. For those places, I give my parents' number (they can have the fuel points or whatever), which makes the data fairly useless.
