It'd be amazing if you listed the price too for the cartridges. I'm sure you could make some money with a sortable list and affiliate links to buy printers based on cheapest price per printed page. What do you think?
I don't think it's something I'd implement at the moment.
Certainly if it was requested more I could contact a few suppliers and roll it out slowly across a few areas however.
I haven't yet decided upon a direction to take it to be honest.
I do have an update planned, I didn't anticipate the current amount of attention to be honest.
