If the city’s transit system is available near you, take it to work instead of driving your car. It’s far cheaper and you won’t have to worry about the added expense or hassle of parking your vehicle either.
When I lived in a larger city, I bought an annual transit pass that actually paid for itself after less than two months of use compared to using an automobile. After that, for 10 months, I basically could ride to work (and to some events) for free. That’s money in the bank.
