Consider asking a cashier for a new membership card and take the membership form home but never fill it out. Why give a fake name when you can give no name at all? The loyalty card still works, and a usage pattern is tracked, even if not necessarilly tied to an identity.
One of my favorite “hacks” is to use the phone number option and put in your local area code + 867-5309 (a number from a famous 80s pop song). You lose out on “savings points” or whatever, but if discounts are offered to card holders you get that discount.
huh? at least in my supermarket it doesn't work, unless you activate it, the new thing being that you can't do that anymore without installing the app. Not sure if that was unclear in my story.
