I posted about www.exceptional-av.co.uk under hot deals but felt they deserved a mention here too.
Not only did I get a great deal on a Q-AV package they allowed my to swap out the free 30m of QED micro speaker cable and replace it with a QED HDMI lead. They through in a free cleaning pack as well.
The chap on the phone couldn't have been more helpful and even took the lead off the shelf whilst on the phone to me as it was the last one in stock. All with the What Hi FI 10% discount.
