MICROSOFT - BV3-00007 DESKTOP 1000 WIRELESS KEYBOARD AND MOUSE
Seems like a good price for an optical wireless desktop package deal - keyboard and mouse. It is £19.33 from PCWorld - you can reserve online and collect at your local store for free, in order to save on postage charges. Otherwise, delivery would be £3.99. (I'd say collect at store!)
