For example, some Miami commuters are ditching their car keys for a Metrorail pass; for two dollars riders can travel from Dadeland to Downtown Miami, regular riders save even more by buying a monthly pass for ten dollars. Tri-Rail trains are perfect for those with a longer commute. Riders can travel from Miami to West Palm Beach for eleven dollars round trip and avoid the hassle of I-95.

If the trains don’t exactly get you where you want to go, why not ‘share a ride’ with South Florida Commuter Services. You can register online for free for car pools of 1 to 4 people or van pools of up to 12 people.

If catching a train or sharing a ride is not your thing, check out promotions that can save you at the pump.

Winn-Dixie shoppers can get a rewards card which gives customers a nickel off per gallon at Shell gas stations for every $50 spent on groceries.

To stretch every gallon you pump into the tank, stick to the speed limit, avoid excessive braking, remove excess weight from your vehicle and make sure your tires are inflated at the proper pressure.
