Where can I buy cheap printer ink from?
You know, you don’t HAVE to just buy a new cartridge. If that printer you’re talking about is a “bubble jet” or “ink jet”, you should just be able to buy an ink syringe at a discount store (like Big!lots or something) and refill the cartridge yourself. I do this all the time. Usually, it works pretty well, although, after a few refills, the print quality goes down (print heads wear out!).
