Adapted from the best selling manga created by Masashi Kishimoto, Naruto Unleashed Complete Series 1 includes Episodes 1-26 of the original smash-hit Japanese TV series.
I have looked at a lot of sites and this is by far the best price I could find. Other retailers prices are listed below:
HMV - £39.99
Amazon - £24.97
Play - 24.99
The complete season 2 is only £17.99 at Zavvi. Other retailers are selling it for similar prices to series 1 as shown above.
Both can also be bought in store for £18 and £20. Student discount of 10% is also available on these, when bought in store.
