Also available online but the £4.95 p&p brings this up to the same price as Play.com. Colours may vary. The shop I was in only had red ones on the shelves.
Noticed that PC World has knocked £10 off the price of the Microsoft 6000 laser notebook mouse as well to £19.99, but the v450 has the smaller receiver.
