> If you walk in to Walmart you don't automatically think you're sharing your shopping habits with thousands of other companies who pay for that data

You can literally buy that data. Either by targeting credit card transactions of people who shopped at a walmart via a broker or you can get more direct data (albeit probably more limited) from them directly here: https://www.walmartmedia.com.

That's the entire problem! Every store doing this should have a mandatory seminar before every shopping visit that outlines every single data point they collect, names every company, intermediary, and consumer of the data they collect directly and clearly, one. by one. These parasitic and disturbing methods only thrive because they have not been brought into the light of day so every consumer can consciously choose what data they want to share at every point. Any other methods except complete informed consent are fraudulent, invasive, and should be illegal. The sheer greed and lack of any morals in ad tech is sickening.
