I have bought this double pack three times now and my initial reservations were confirmed with the last pack I bought. The colour cartridge just does not last a reasonable amount of time. I started to use this and printed off just 4 photos and a letter before the colour cartridge ran out. At first I thought it could be my fairly old printer but this weekend I went out and bought the HP22 cartridge from a shop. It wasn't an XL one - it was just the same as the one from Play.com. Although it cost me 18.00 pounds for the one cartridge, so far I have managed to print out 10 photos, 2 letters, a 16 page graph and the colour cartridge has barely been used. I can only conclude that there is something not quite right with the double packs I've bought from Play.com. I won't be buying them again although I still recommend this excellent site for DVD's and books etc.
