The only one of those I do is for the grocery shop, and frankly I’m not even sure why since it doesn’t do much. They give me a couple bucks off and a gas discount but only at one shop I’m pretty sure inflates the standard price to accommodate it. Never sent an email or a text bugging to come buy anything though and it’s only based on my phone number and could even be an anonymous paper card with no sign up, but no gas discount for the card since it uses the phone number to activate that at the pump.

A nickle off a soda is far from the cost to get your app on my phone.
