I've been after some Lightscribe CDR's for a while and this was the best deal I've found for Coloured Lightscribe Discs (even beating ebay!)
Lightscribe enabled drives enable you to flip over your CD and have the laser print a greyscale image on the front. Perfect for making professional looking CD's of your favourite music or movies.
HP have recently released these coloured discs which were previously only available in Gold.
Delivery varies between £2.50-£5.99 but I would suggest its worth putting in a bulk order to get best value. The discs are packaged in a 10-disc HP spindle.
