Very Low Bills (100 Simoleons) by mgomez at Mod The Sims

This mod will eliminate all of that and modify bills.py to return only 100 as its value when get_bill_amount is called. Translated into normal-speak, that means you get to pay only 100 simoleons! You’ll live like a king in the Cayman Islands with all of your expatriated accounts and no taxes to pay!
