In work yesterday walking past the game and saw this on the shelves for 24.99 i am pretty sure its the cheapest around and not been posted before, if it has ignore this and mods please delete.
I get staff discount as well so i will be getting it for 22.50 :)

In my local store i work in (speke, liverpool) they have either a 4gb sd or a 4gb micro sd for £8 each.
This is my first deal post so hope its a good one.
