Rihac Premium Quality Continuous Ink Supply System
SAVE 94% of the cost of OEM cartridges
That depends how much you print. Obviously, the more you print the more you will be saving.Consider it this way, the HP cartridges that came with your printer contain 17mls of ink in the colour cartridges, and 59mls of ink in the black cartridge.
The HP88 colour cartridges retail for around $42 and the black cartridge HP88 retails for around $58 (prices correct as of Sept 2008 via officeworks online).
So this equates to $184 for one set of cartridges which contain 110mls of ink = $1.67 per 1ml of ink. RIHAC compatible refill inks for the HP 88 Black pigment based ink is $19 per 100mls = 19c per ml, and HP88 colour dye base inks are $13 per 100mls = 13c per ml, so around a 94% saving.
In our smallest set of replacement inks (100ml of each colour x 4, total cost $52 for 400mls of ink), there is approximately 2 black and 18 colour cartridges of ink . To buy the same amount of cartridges would cost you $870
Equivalent to approx2 Black & 18 colour cartridges cartridges which would cost you over $870.00*
