Being a poor pensioner with only £3 a week pocket money I bought my latest re-manufactured ink cartridges from
Printer Cartridges, Cheap Ink Cartridges, Printer Inks, Laser Toner & Inkjet Cartridges
They work and are less than one third of H.P cartridges.
I'm not connected to them but if they want to send a few freebies for the advert I'll not object.
