Yeah, ultimately it probably does end up selling more cartridges over time. Like even with the refillable ones you still gotta replace them eventually because of the print heads. Honestly, the more I think about it I think I’m just gonna continue to not print things out at my house and just use the Kinko’s when I need to for a dime a page. I mean how much do I actually print out anyway. This is the same math I did when decided not to buy another ink cartridge last time my printer stopped working
