Saw this is in Game earlier whilst browsing in Gallions Reach (Beckton).
I don't know if it is store specific or just instore!
£29.99 if purchased with anything in the store. There is NO minimum purchase price which means you can buy the cheapest item and get this with it.
Sorry if I have made any mistakes, I use this site for deals and I think I've found one! Couldn't find another deal similar to this and if there please delete this post and forgive me.
