This. As someone living in Japan, I would love an option to drop a dollar to read the economist or such for a day.
I rarely subscribe as, between work and a new son, rarely have time to keep up to date on a particular site, and the background stress of paying for something I'm not using is frustrating.
So just make it so you can Apple Pay your way to a day's access to the current news for a buck.
Once someone has done it two or three times, offer a subscription to them.
