Whether you are paying extra if you don’t use a discount card or you’re paying less if you do use the discount card, either way you look at it, there’s more money in your pocket if you walk out of the grocery store after using a discount card. So you have money by handing over data to whoever the store is selling it to.
Why would you think of using a card (taking an action) as the default, as opposed to not using a card (no action) as the default?
