Add on purchase

Good game and it is nice...can u please make the add on purchase for the new map either on the front page of the game or somewhere in options or something? And/or have the add on purchase on this iTunes page...I think u can purchase the add on map when u get up to the game itself, but people like to purchase the add on map right now..thank you!
