    This is a classic State Machine problem. Use the total deposited as the state. Use transition events like vend, addcoin and cancel. Many State Machine examples can be found online a good example for this problem is here: http://www.gamedev.net/blog/802/entry-2217738-system-design----finite-state-machines/
