Especially true of ‘loyalty’ cards. I made a purchase of hand sanitizer early in the COVID pandemic. I purchased it at a grocery store with a loyalty card.
It was recalled and I received notification from the manufacturer about the recall. They had to know I had purchased it, and my contact (email) info, from the loyalty card.
There’s nothing Big Brother can’t find out about us!
So they’re actually keeping a list from where I’ve everything we buy at a grocery store if we have the loyalty card!
