Well, as long as people realize their data is sold by food markets, I am personally OK with it. That said, to not get the discounts (thus not sharing your information) is leaving money on the table.
Also, if you are not part of a loyalty program, and you use a credit card, it is very possible that your purchases are still tracked - all it takes is cooperation between store and credit card company.
- fragmede 4y agoWhy does it take cooperation with your credit card company? The supermarket can uniquely identify the card used for payment, even if they don't get the full credit card number due to PCI.
- mark_l_watson 4y agoYou are correct.
- JohnFen 4y ago> That said, to not get the discounts (thus not sharing your information) is leaving money on the table. Not if you shop at a reasonable store. And even if that's not an option, I don't consider it "leaving money on the table", I consider it "buying privacy".
- mark_l_watson 4y agoI admit some inconsistency in this. I am careful on the Internet (I use Proton Mail, and almost always use private browsers tabs for following links), but not for purchase data.
