I love smart technology that works with you and the planet. HP Instant Ink is one of those ideas that makes sense. Register online, pick your plan (I went with the $4.99 per month option but can change at any time) and get printing. They track your usage and ship your ink when you need it before you run out. No worries about picking the right replacement at the store. Cartridges are recycled. Ink is cheaper. HP quality. What’s not to like? Check it out. HP Instant Ink
