I spotted this decent deal on the Gamestation website while I was testing out the new £3 discount code. Gamestation are offering "Naruto Clash of Ninja Revolution 2" (Wii) for only £14.98 with free delivery.
The next cheapest online price I can see for this game is £19.79 @ Simply Games, so I think it's a good price from Gamestation.
I've not played the game myself, but it gets an impressive 8.2/10 on IGN, and 7.5/10 on Gamespot.
Might be worth a play!
