ETA: Aldi representing a store without a loyalty program
A significantly more complex hypothetical that I don't think anyone is doing yet: With digital price tags and customer tracking you could show different prices to different customers in-person. For example, when Alice goes to the eggs it could say $2 and when Bob goes to the eggs it could say $4. Then you just need to track the customer to the register to make sure you give them the price that was displayed. I believe the amazon "go" stores were doing the whole customer tracking thing so we already have the necessary tech demonstrated in real stores.
This already happens. We've been getting personalized coupons from our local store for 15+ years now.
This is already happening at Lidl. I was standing in line one day and the lady in front of me asked if I had the app, because there was something like a $5 off $50 purchase coupon in there I could use. I did have the app and checked, but my coupon instead was for $15 off $150.
Thinking a little more deeply about it, every time I go there I tend to spend an average of around $125. My hypothesis is that they have that data and know a customer's average spend, so they tailor the coupon's dollar amounts to the customer to entice them to spend slightly more than they usually do.
Banning a pricing model should be unconstitutional
That's a simplistic example, but we've been lectured about consumer choices, invisible hands of marketplaces, demand curves and marginal value for so long I'm genuinely shocked that ill-defined "predatory pricing" is the issue we see in the news.
While I agree with the intent of this law, I don't think it will be effective. If you have a system capable of jacking prices up you can just multiply this calculated delta by -1 transform that into a discount.
To effectively prevent this practice you probably need to ban any kind of personal discount. I don't think we will ever see such law, nor do I think this would be a good idea.
