Instructions:Use the code ZQ603 at http://www.littlewoods-online.com/rf/navigation/home/index.do to receive a £15 discount. I used it to get a wired Xbox 360 control pad for £10 including postage! Usually it is £25.
Similarly if you go through http://www.lxdirect.com/press and enter the code ZG0077 you receive a £13.50 discount (£10 + free postage. I used this code to get the official Xbox 360 remote control for £10 rather than usual £23.50.
No idea about expiry dates for these offers but they worked for me this morning so use them while you can.
hope it works as good for you as it did for me =)
Official controller and remote control for £20! =D
