Maximize Your Cash:
-------------------
You can send shoppers on their merry way after filling up most of their carts, 
but try to hold out for a full cart (x2 cash) or even better a full cart made 
up of all the same color items (3x cash).

The Warehouse:
--------------
Put useful pieces (like 1x1 buttons) in the brown warehouse area to use later. 
You can also warehouse items that are about to fall off the conveyor belt.
