I need ink for my printer

My printer is still fairly new, I just got it in May. But I'm already out of ink! When you buy a printer, they give you two cartridges. However that ink never lasts very long. I don't even use my printer that often. I went to print out my homework assignment and it only printed half and the other half was basically blank. I'll use Cartridge Finder to help me find the cheapest ink. They compare prices across stores for me so I get the best deal.

I just hope I don't have any more homework before I get my new cartridges.
