Re:...unless you refill (Score 1)

Ink costs $6.80 per kilogram, that's a lot less than $100/gal. Also, there's no use to refill cartdriges like nuts, just use a continous ink system (CIS), you can find for all printers now. I know a nice company that will send you 10 kilograms of ink and two CIS for a hundred bucks, you can print with that ink maybe 20K pictures so what is it, around 0.5 cents per picture cost. You can even sell some of ink on ebay and make some pocket money.
