I hope I posted this in the right section as it's not a voucher, but a link to the web site that knocks the above off.
I have a discount book that has a list of sites & codes that you can use and one of them is for 50p off every CD and DVD at CD-WOW. If you click on the link it will take you straight there. In case you want to pass it onto anyone the link is: http://www.cd-wow.com/sports
You don't need to enter any codes at the checkout as the discount comes up on screen
