I see you have not bought an HP printer lately: https://instantink.hpconnected.com/us/en/l/v2

I'm surprised that HP hasn't shuttered Instant Ink because of the terrible PR they get from people that don't understand how the service works, subscribe for a month for $3, then are all Surprised Pikachu when they cancel the service and they can't use the ink anymore.
