I know a ton of people who use Cash App's card for that. Seems like it works well for them. (I don't use it personally)

I loved that card for the $1 off at any coffee shop until they changed it. It's still ok, but now you have to make 5 purchases with the card to get 5x$1 off.

Huh, they might be A/B testing that. I still have the original $1 off any coffee shop (min. $1.50; every 30 minutes). When did your deal change?

A couple of months ago. On podcasts I listen to, I've heard other people talk about it changing. Basically the deals all get 'locked' until you make a certain number of purchases to unlock them again.

The idea that gas stations and restaurants have to be regarded as "sketchy stuff" seems quite sad to me.

Both of these are only sketchy because the US refuses to modernize. Restaurants need to switch to portable readers that work with contactless/phones. Gas stations also need to accept general contactless and not just whatever special gas card they have.
