This is the Anime-online deal of the week; unfortunately it's not a complete set so is not such a good deal as some lately.
You can pick up the part 1 discs for £8.85 from Zavvi / the hut.
Despite that this is a great anime and well worth adding to your collection.
"Balsa the spearwoman is a wandering warrior, who takes on the task of saving lives, in atonement for a past sin. On her journey, she happens to save a prince, and is tasked with becoming his bodyguard. And he is going to need one, for his own father, the emperor, wants him dead."
Note: I panicked that this set was in actually in 4 parts and not two; Anime On Line show the running times for the part 1 and 2 sets as 175 and 150 minutes that is clearly wrong as other retailers state each set has 13 episodes.
