I'm a teacher who uses ink fairly quickly to create centers and activities for my kindergarten class. My trusted printer died and I needed a new printer. I bought a Brothers printer for a low price but the ink actually cost more when it needed to be replaced. I researched and compared different places to buy ink refills and this was the cheapest for the amount I got. I am happy with my purchase and will continue to shop from this seller. I had fast delivery and overall I'm happy with my purchase.
