It is easier to go to Staples and buy the ink rather than wait for a robot to mail it to you. Dont sign up for hpink it dont save you money and you could end up in the middle of something and run out of ink
I prefer to use original ink with my current HP Printer as I've used refill companies and had problems with clogging and expiration dates making brand new cartridges unasable.
These ink cartridges are great. They add color to my world and let me print whatever I want. Although I use mostly the black color the other ones are vibrant. I used an off brand once and it didn't compare to HP's OEM print cartridges.
