The kids had to do a school project and I was out of color ink for my old HP deskjet 835C. Wal-Mart didn't have the cartridge for it, but they had a Canon with both ink carts for $29.99. It works great, but is now out of ink after year. It costs about $40 for both ink carts and you can get the whole printer for $3o. I hate to throw things out that work, but it doesn't make sense financially to replace the ink.
