The cost of ink is precisely why I don't print photos at home unless they're part of a DVD cover I'm making for home movies. It's cheaper to have a lab do it than it is to do it myself on an inkjet. Better quality, too. I have a friend who prints his photos at home on his printer and he's always complaining about having to go buy ink for it. I keep telling him its better to have it printed somewhere else - even at a one-hour lab.
