Credit card doesn't give them your phone number and possibly email. Also they use loyalty system to post normal prices. So they can still charge higher prices to everyone who forgets or doesn't use the loyalty cards.

Same reason they started doing digital coupon bullshit that needs to be scanned.

As well. As data collected from your phone via their app
