My Canon printer quit last night and I have 7 unopened boxed cartridges that don't suit my new printer.
They are not genuine Canon, but a clone brand I've used for years.
So if your Canon printer accepts C-651 and C-650 they're yours for the asking. If you're in Brissie you can collect them, otherwise you can pay the postage (my generosity has limits
)
They fit many of the MG series and a couple of MX and IP series.
