Gamestation have an offer on a range of their pre-owned stock... except as I entered the store, they said they were closed, but this was the one game I noticed in the offer.
I will pass the store Sunday to check the other offers.
Next nearest price is £8 from cex

OK, so not a huge saving, but still a few quid saved.
On ebay they have been selling anywhere between 6 and 12 so it's probs the best price around.
