I don’t have a printer anymore, but stumbled across this at Big W in Brisbane. A bunch of clearance printer inks for crazy prices. Not sure if nationwide
Brands include Calidad and Brother
eg. Calidad 3x colour ink $2 (save $36)
eg. Brother colour value pack $18 (save $86)
Hopefully it helps someone
Maybe very old stock and getting close to the end of shelf life. The inks do destablise after a period of time.
