I needed ink. I didn't want a compatible ink, I wanted the genuine stuff. (I've never had much success with compatibles). I was unable to buy the ink from the shop where I bought the printer a few days before (Tesco at that), so went to my usual source, Amazon.
I found this twin pack of extra large capacity inks at a few pence more than individual inks would cost in normal retail outlets. I made the purchase, and waited.......not very long though. The delivery time was superb, and the inks turned out to be the genuine article. I have nothing but praise for the supplier.
