Cheapest elsewhere online (and in stock) is HMV @ 6.99. Saw this at Trafford Centre branch of WH Smith. In store only (14.93 online).
Thought this was a great offer!
This was as part of a sale so there were lots of other good deals on games too including Sports Party for the Wii for £10. Xbox and PS3 games were on sale, but not sure of titles sorry.
