Yeah, printers are ridiculously cheap. They'd probably give them to you, except then you'd just get a new printer rather than buy a new cartridge.

I've got a couple year old all-in-one with the six cartidges. Yellow, light and dark Magenta; light and dark Blue; and, Black. I love it. When one color runs out, I can just replace that cartridge for about $11.00 (Used to be $10.00. Still, better that the higher priced 3-in-1 color cartridges most printers use.
