10 tips to save on your car rental in St. Clair County

  1. Use filters to find the right car: Refine your search by vehicle type and specific features. Whether you require an SUV for additional space, a convertible for summer enjoyment, or an economy car for budget-friendly travel, leverage the filters on Expedia to discover the ideal vehicle for your journey.
  2. Book in advance to help lower costs: Rental prices can vary significantly based on demand, so it's advisable to secure your car well ahead of your trip. By booking early, you’re more likely to access lower rates and better availability, particularly during peak travel seasons.
  3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to manoeuvre in crowded areas. Mid-size rentals strike a good balance between price, comfort, and fuel efficiency.
  4. Age guidelines: Drivers under 30 may encounter higher deposits or daily surcharges, and specific vehicle types—such as SUVs or premium models—might not be available. This can also apply to renters over the age of 70. Always review the age requirements before finalizing your booking.
  5. Check fuel policies: Some rental companies require a full-to-full fuel policy, meaning you must return the car with a full tank to avoid additional charges. This is usually the most advantageous option. Others may offer full-to-empty or prepaid fueling options, which are also acceptable. Just ensure you return the car empty in such cases.
  6. Save on city and airport pickups: Picking up your rental car at airport locations often incurs a surcharge, though the added convenience may justify the cost.
  7. Know your payment options: Many car rental agencies only accept credit cards for payment.
  8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provide peace of mind if something unforeseen occurs during your trip. It's easy to add car rental insurance when booking through Expedia.
  9. Consider unlimited mileage: If you're planning extended road trips, look for rental options that include unlimited mileage to prevent additional costs.
  10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
