I have been on line to buy a full set of ink cartridges for my Canon Pro-300 printer and I came across a company called Cartridge Discount which I have never used before. The are hinting at being a discount outlet to which I emphasise is total RUBBISH! For a full set of Genuine Canon Cartridges from Canon is around £160 or thereabouts. My usual place I buy them from is called the Cartridge People based I think in Cheshire Is actually £134.20 for genuine Canon. But these people are selling non genuine Canon ones singly. (They don't have full sets) but for 10 of all the colours is over £240. That is what was quoted and I was not just looking at their web pages. I wonder what planet they are on?
