I have recently bought HP cartridges from The InkClub click here. They were cheaper than most for originals - and they delivered within days. They have one charge for P&P so it pays to buy a couple at least at a time. I'll certainly use them again
I have an HP 815C and I get all my ink from Choice Stationery at click here Just checked the prices and compatible black is £8.50 against HP price of £22.62 and the colour is £13.89 against HP price of £43.99. I know which ones I would buy. Choice Stationery prices include VAT and postage.
