HP 305 Tricolour Cartridge (Eaglesham, G76)

Has anyone got an HP 305 Tricolour cartridge. This does not need to be new it can be used or partially used. I need it to fit into second hand HP Envy 6400 printer which is lacking this cart and therefore cannot be installed in my pc as both carts are needed. At this point I don,t want the expense of purchasing a new 305 cart as the printer may have other faults
