Saw this mouse in Tesco Blackpool this lunchtime for half price. This cordless optical mouse comes with a nano receiver. This is now sold out online but is still avaible instore. they did the same with the dodgy pink version a few weeks back.
I actually bought the piano black with orange stripe one a month ago in pcworld for £25, but i think this silver grey one looks better cos the finger print marks wont show as bad
