This has been previously listed, but got an e-mail through today saying it's been reduced to £19.99.
This offer is available to VIP customers only, but all i needed to do was tell the sales guy that I had an e-mail offering it for 19.99.
It is strictly 1 per VIP customer only, and available instore only.
I've linked it, but the online price is 29.99. I have just bought one for £19.99, and it's playing in the background now. All very nice
