This is a trade voucher I got from CEX (in Cardiff) on Tuesday (so it is valid until February 12th 2009). I traded some games for Burnout Paradise, and £12 was the excess. I can't be bothered to go back to Cardiff (closest CEX to me) to use this, really.
This voucher can be used in ANY CEX store, and I think also online, though I'm not sure how that would work.
P.S. As always, pics. and phone number provided on request.
Paypal, cheque, cash or postal order. Voucher sent once payment has cleared.
