Refill ink is the way to go. I bought these ink to use in my Brother MFC- J430 printer. All you need is a set of refillable cartridges. A set of original Brother Cartridges cost more than $50 generally. Each cartridges contain about 30 ml of ink. This package comes with 4 litres of ink, one litre for each colour. If you do the the maths the black for example is 1000ml vs 30ml in the original cartridge. With these ink going for little over
$ 60 for all four, this is really the way to go.
I am ink the refill business, so i refill ink for persons. These ink said for use in Brother printers, but they work ok in Cannon and HP.
