Cash stack
(Cash or $) is a permanant currency in The Simpsons: Tapped Out. It can be collected by finishing characters' jobs, collecting income from buildings or winning on the Scratch-R. The most expensive building currently available for cash purchase is the 50ft Magnifying Glass which will cost the player 3 Million cash to buy. All of the main questline buildings are bought with cash, and so are most decorations. Cash has been in the game since it's official launch in February/March 2012, and the player may have up to $99999999 in their account at one time.
