Thanks for all the help guys, however despite a fairly extensive search it looks like there are no available copies in the UK, or at least not that can be found.
@PFBeginner - thanks but unfortunately i'm attempting to buy it for a nephew as a present. He's keen to get into more nerdy related activities - it looks like i will be going to get him a copy of the 4e Red Box instead.
Im advised that its been out of stock/unavailable for some time now.
On that note id like to say (just encase a representative of paizo is reading) that they would do well to remember how important the Red box and other type of starter kits were in term of making us as kid develop a lifelong roleplaying habit, and not having a starter kit available (for an entire country) will inevitably mean that those childhood memories (and brand loyalty) wont be developed for pathfinder but a rival system (d&d in this case)
Not a rant mind, just a unfortunate fact. And i was sooo looking forward to playing through the kit with him!
