Yeah I've not seen it retail here in the UK. I bought it several months ago on gamersgate. Not the co.uk site though, their main one (in US $). Works out a bit cheaper after conversion.
Its a fantastic arpg imo. Can't praise it enough. Not dumbed down like so many these days. Have to really think about things, like solving some quests etc. Great humour and a nice world to explore. It isn't openworld but the maps are big and interesting for the most part. Thoroughly recommended!
