I started using HP Instant Ink last year as it seemed my “Last longer “printer cartridges were not doing that and for $60
Or so a cartridge a few times a year, it was awfully expensive. I just pick that I print 100 or less copies a month and pay a flat fee($5) and if I don’t use them I can roll them over for next month. I think 5 cents a piece is cheaper than my library charges.
