Instructions:This code has just worked for me for both my accounts. It is valid for orders on pre-release CDs/DVDs.
The best offer I noticed was the David Bowie Reality/A Reality Tour [CD + DVD] for £5.97. Given the points are worth £6.00 when used on clubcard deals, you are making a 3p profit!
Personally, I've ordered the new Groove Armada CD for £8.48 (play.com £8.95, hmv £8.99) and UP! DVD for £9.97 (£9.99 play.com, £15.99 hmv.com).
Edit : Also XXFEB200-1 for 200 points (worth £8.00 on clubcard deals) on pre-release Games and Blu-rays
