You can be eco-friendly and save a few bucks by taking your empty ink cartridges to the nearest Walgreens for refilling. The advertising said that refilling can be about 50% cheaper than buying a new cartridge. I wasn't paying attention to the Clark Avenue Walgreens to see if they had one, but I know the one on W. 117th Street does. This is an even better option than simply recycling the old ones.
