There is exactly one reason why I wish a supermarket would contact me out of the blue: a recall, since they would in theory know what I purchased if I used the card, so no need to first hopefully hear about the recall, then try to figure out if it applies to me.

That said, I've never heard about that as a benefit from a market in the US, just discounts on food items (or put differently, upcharges if you don't use a card).

Not that we have GDPR-level protections here either.
