Just picked this up instore at PC World but it also appears to be online. The pack consists of the Microsoft LifeCam NX-6000 (£52.50 on Amazon) and also the Microsoft Wireless Notebook Laser Mouse 6000 (£22.52 on Amazon).
Got this for the bargain price of £34.97. It was on a yellow sticker in store so I suspect it is on sale but it didnt say the previous price.
I'll let someone a little more informed work out the price with the voucher and quidco. Not sure which order they get applied!
