Maybe. When you sign up for Amazon Prime, you see lower prices on some products when you're logged into that account. Same with Costco, if you have a membership, you see lower prices on some products in their app.
I worry that rather than "fixing a problem" that may not exist, this creates a new problem.
Look at how PSN is doing dynamic pricing for their games. That's what this is trying to prevent in grocery stores.
Sometimes I get a flyer in the mail for grocery discounts. That's not the targeted surveillance pricing being discussed.
