Peach Snap'N'Print Cartridges These "Starter Kits" give you a re-usable print head and three disposable ink tanks. When you run out of ink, just replace the ink tank at a fraction of the cost of an original Canon cartridge. The initial out-lay is less than the cost of 3 OEM Canon cartridges and the refills work out about half the price of replacing an OEM. Each colour Peach Ink Tank gives you 21ml of ink (7ml x 3) compared to 12ml (4ml x 3) in the OEM. The black Ink tanks give you 22ml of ink rather than the 16ml in the OEM making for a further 75% saving!* *based on approximated volumes and costs of Canon PG-40 and CL-41 cartridges at 29/09/2006
