I wanted a pack of 25 DVD-R and this is the cheapest I could find them by a long way. Much cheaper than the £1.89 for the pack of 10!
Website copy and paste:
Infiniti DVD-R's are among the highest of quality, and lowest in cost, great for general burning for backups etc.
Frosted Tops (Classic Finish)
Protective coated, for better data protection
Multi speed (up to 16x compatible)
25 discs per pack in a strong protective 'Cake-Box' with securely interlocked base and shell.
