I like that i can buy ink and have it delivered to my door a day later. I have seen that the cartridges do not have a full container of ink. And sometimes the color is more dark gray than black.
[This review was collected as part of a promotion.] I bought this a month ago and got free shipping for one day delivery, so when I needed a color ink cartridge (HP 22) I placed another ordered from the site with photo paper.
