We are doing a pretty awesome project at home that involved us printing some stuff. I do not print at home much at all, and have not printed in color for about 5 years at least. Ink is so darn expensive and I was actually looking at getting a new printer instead of dropping $80 on ink for our project. Years back I refilled my own ink, but it was messy and quite the pain. A friend mentioned Cartridge World and it was a total head smacking moment.
I brought in my 4 empty cartridges and they were swapped out with recycled and filled to the brim ones for $35 after tax. Just a cartridge of black costs that much retail. Chatted with the guy working there and it was pretty interesting. I will go back again.
