If it’s paid you are still the product just more valuable

I don't get this. I'm the product of my grocery store?

The line gets blurry. But it depends if you have a loyalty card. A grocery store is a market-place where many large companies can sell their stuff.

Your grocery store is probably collecting data about you and making money from it. If so, then yes, you are the (or, more accurately, a) product.

But at least you can foil a lot of that by putting your phone into airplane mode before getting anywhere near the store, paying in cash, and not using "loyalty" cards.
