In addition to FinlyBoost rebates on cross-search sites and rental car companies, you can also save money on rental cars with eligible memberships.
In this section, we’re going to highlight two popular membership programs that can help you save on car rentals.
With a Costco membership, travellers can access discounts at car rental companies like:
To access these savings, simply book through Costco Travel by following these steps:
Keep in mind that a Costco membership comes with an annual fee, so you’ll want to make sure you’re a frequent enough shopper to take advantage of these associated deals.
AAA offers more than roadside assistance, members can also reap the benefits of discounts at Hertz – saving you up to 20% on rental cars.
Simply use a designated discount code and present your AAA membership card to score these specialty savings.
Note that there are membership tiers with associated annual costs, so make sure that you’re using the provided benefits enough to make the most of the yearly expense.
With impressive catalogues stocked with various makes and models, it can be tempting to rent a luxury vehicle so you can travel in style.
Still, the best way to save money on the actual rental car itself is to opt for an economy car. Economy cars are usually the cheapest rental option and are typically a smaller pick, so ensure that your entire travel party (and their luggage) can be accommodated.
As the most budget-friendly option, economy cars are oftentimes the most sought-after rental cars. This can actually work to your advantage. If you reserve an economy car, then come to find out by pick-up time that they’ve run out, there’s a chance you could be upgraded to a better alternative.
Usually, rental car companies will charge an extra fee for additional drivers – these fees can start at $10 a day. That’s why picking a designated driver is the most cost-effective way to secure your vehicle.
Sometimes, certain rental car companies will waive the extra fee for spouses or domestic partners, as long as you both have the same home address on your driver’s licenses or you’re enrolled in a specified membership program.
Avoid getting roped into unnecessary insurance add-ons provided by the rental car companies themselves by reviewing your personal and primary insurance policies. Oftentimes, these policies will cover you and help you avoid daily coverage costs.
You can also take advantage of certain credit cards that come with rental car coverage. To learn more about these insurance policies and the cards that offer them, check out our Credit Card Rental Car Insurance blog.
In addition to coverage, some credit cards come with perks that help you save on rental cars.
Some popular credit card issuers with these types of deals include:
At Finly, our top-rated BMO credit card with car rental discounts is the BMO Cashback World Elite Mastercard – with 25% off the base rate of rental cars at participating National Car Rental and Alamo Rent a Car locations.

Lots of times, renting a car at the airport comes with extra charges due to increased demand. These extra charges often include facility fees and taxes.
If possible, try to take public transportation to a nearby rental location off of airport grounds, or at least compare the price against what the airport charges and any costs associated with taking you offsite instead.
Renting a car can be budget-friendly, you just have to know where to look, how to optimize, and what to choose.
To make this criteria simple for you, we’ve curated the best tips on how to cross-search and boost your rental car bookings, how to make the most out of memberships, which type of car will save you the most money, and which credit cards come with the best rental car perks.
