http://www.svp.co.uk/acatalog/Epson_Stylus_Photo_R300.html I'm not affiliated with this site or anything. But 2 Blacks + 1 of each of the other 5 colors for 8.99 is cheap. That equals £1.28 per cartridge, BUT its buy one get one free!!!! So its 14 cartridges for 8.99 which is 64p each!! 1.99 postage which took one day for mine to arrive. Installed the black, the printer didn't even realise it wasn't an official epson cartridge. I would highly recommend.
