More Ways to Save on Car Rentals

Sticker shock at the rental counter is a rite of passage. The base rate looks fine, then taxes, airport fees, and a young-driver surcharge land on the screen, and the total doubles. Here is the short list of moves that actually move the price.

• Apply a corporate or association rate first. AAA, Costco Travel, USAA, and AARP usually shave 8 to 20 percent off the base rate, plus waive the additional-driver fee for a spouse. Costco Travel is the heaviest hitter on weekly bookings, especially with Avis and Budget.
• Compare aggregator and direct rates side by side. Kayak, Priceline, Expedia, and Hotwire pull contracted inventory that direct sites do not always show. Then check the rental brand directly because loyalty members sometimes see a member-only rate that aggregators miss.
• Pay now, not later. Prepaid rates usually run 10 to 25 percent below pay-at-counter, with a tradeoff on cancellation flexibility. If your trip is locked in, prepay.
• Skip the airport pickup when you can. Off-airport branches dodge the airport concession recovery fee and the customer facility charge, which together add 10 to 18 percent to the bill in cities like Los Angeles, Boston, and Orlando.
• Decline the counter upsells you do not need. Loss damage waivers cost $20 to $35 per day, and most major credit cards already cover collision damage on rentals if you decline the rental company coverage. Verify with your card issuer before the trip.
• Refuel yourself. The fuel service option at the counter looks convenient and runs $9 to $11 per gallon. Filling up at a regular gas station before returning cuts that to whatever the local pump price is.
• Check GrabOn before the final click. The Car Rentals hub aggregates active codes for Hertz, Avis, Enterprise, Budget, Sixt, Thrifty, and Dollar in one tab, plus the seasonal sales banner from Kayak and Priceline.

Best Car Rental Offers Available on GrabOn

Top coupon-code offer. Sitewide brand codes from Hertz and Avis run 20 to 25 percent off base rates on midsize and full-size cars when the rental is at least three days. Most expire fast, so grab a fresh one before locking the booking.

Strongest no-code deal. Free single-class upgrade promotions show up at Avis and Budget through most months. Book a midsize, get a full-size or premium for the same price with no code to enter, just the right rate plan selected at search.

Bank or payment savings. US-issued cards from Capital One Venture, Chase Sapphire, and Amex Platinum carry primary or secondary collision damage coverage on rentals, which lets you decline the LDW. That decline alone saves $20 to $35 per day, more than most coupon codes.

App-exclusive offer. The Hertz, Avis, and Enterprise apps push flash codes a few times a quarter, usually 10 to 20 percent off mid-week rentals. The Sixt app also unlocks express pickup, which matters if your flight lands at peak counter hours.

First-time user discount. New loyalty signups at Hertz Gold Plus Rewards, Avis Preferred, and Enterprise Plus often unlock a one-time $25 to $50 off code on the next rental. Free membership, two minutes to sign up.

Seasonal sale highlight. Memorial Day, July 4th, Labor Day, and Thanksgiving travel windows trigger 25 to 30 percent off promotions across Budget, Dollar, and Thrifty. Aggregators like Kayak and Priceline mirror these with bundled flight-plus-car deals during the same windows.

Deepest category discount. SUV and premium vehicle rentals see the steepest percentage cuts during shoulder seasons, January to early March, and late September to early November. Compact and economy class stays close to retail year-round because demand stays steady.

Brand-Specific Programs Worth Joining

Loyalty Programs

Hertz Gold Plus Rewards, Avis Preferred, Enterprise Plus, and National Emerald Club are free and worth joining if you rent more than twice a year. Benefits include skip-the-counter pickup at most US airports, a guaranteed vehicle class on the Emerald Club Executive tier, and faster point accrual during quarterly bonus promotions. Sixt Advantage Circle and Budget Fastbreak run smaller versions of the same playbook.

Corporate, AAA, Costco, and AARP Rates

Discount rate codes from AAA, Costco Travel, USAA, and AARP usually beat publicly listed coupon codes on weekly bookings, especially with Avis, Budget, and Hertz. Costco Travel often bundles a free additional driver and a tank of gas waiver, which together can be worth $40 to $80 on a five-day trip. Verify membership at the counter; the agent will usually ask for a card or membership number.

Subscription and Rideshare Programs

Hertz, Sixt, and Enterprise all run monthly subscription tiers for renters who need a car for two to four weeks at a stretch. Pricing lands between a daily rental and a long-term lease. Hertz also runs a dedicated Uber and Lyft rental program with weekly rates aimed at gig drivers, which is a different rate sheet from leisure bookings. Turo, the peer-to-peer car sharing marketplace, integrated with the Uber app in May 2025, allowing Uber users across most of the US to browse and book Turo vehicles directly - the service is not available in Oregon, New York, or Washington. Zipcar offers hourly and daily car-sharing at a Standard plan of $9 per month or $90 per year, with a new beta offering a Lite tier at $5 per month for occasional urban trips and a Plus tier at $19 per month for frequent renters.

Platform Guide: Major US Car Rental Options

Enterprise Rent-A-Car

Enterprise is the largest car rental company in the United States by location count, with over 9,000 US branches, including more than 230 airport locations. All pricing is in USD. The fleet runs from economy sedans and compact SUVs to passenger vans, cargo vans, and premium vehicles. Foreign drivers with a non-English license should bring an International Driving Permit (IDP) to streamline the rental process, though Enterprise accepts most valid foreign licenses - an IDP is strongly recommended rather than strictly required. Renters must be at least 21 years old; drivers aged 21 to 24 pay a young-driver surcharge of $20 to $35 per day. Find current Enterprise promo codes and member-rate deals on GrabOn.

Hertz

Hertz operates at over 500 US airport locations and hundreds of off-airport branches, with all prices quoted in USD. The fleet includes economy, midsize, full-size, premium, SUV, and luxury classes through the Hertz Prestige Collection. Hertz requires an IDP if your home license is not printed in English - this is enforced at the counter and is not a soft recommendation. All members of the free Gold Plus Rewards program can skip the counter at participating US airports and waive the additional-driver fee for a spouse or domestic partner. Points are valid for five years from the date earned and can be redeemed for free rental days on any car class with no blackout dates. Find active Hertz coupon codes and Gold Plus member offers on GrabOn.

Budget Car Rental

Budget operates at over 850 US locations, including most major airports, with all pricing in USD. The fleet covers economy through full-size SUVs, minivans, and trucks. Budget "may require" an IDP for non-English licenses - enforcement varies by location, so foreign drivers should bring one to avoid delays. Budget Fastbreak is free to join, and the most practical reason to sign up before any trip: members skip the counter on direct bookings, return to a dedicated drop-off area, and receive a receipt by email. Fastbreak benefits apply only to reservations made directly on Budget's site or app, not to third-party aggregator bookings. Find current Budget discount codes and Fastbreak-compatible promo rates on GrabOn.

Turo

Turo is a peer-to-peer car-sharing marketplace where private owners list their personal vehicles for rent. Pricing is in USD and varies by vehicle, location, and host. The platform operates in over 5,500 US cities with more than 1,600 makes and models available, from economy hatchbacks to trucks and luxury cars. Turo is currently unavailable for bookings in Oregon, New York, and Washington state. Foreign drivers in the US must present a valid international license plus an IDP and a matching passport for identity verification - Turo's official policy accepts many foreign licenses, but an IDP is required at the US platform level and recommended to avoid host-level rejections. The minimum age to rent in the US is 18.

Zipcar

Zipcar is an hourly and daily car-sharing service for urban and campus users, not a traditional rental company. It operates in hundreds of US cities and on many college campuses. All pricing is in USD. A $25 one-time application fee applies when joining; the Standard membership costs $9 per month or $90 per year and includes gas, insurance, and up to 180 miles per day. As of April 2026, Zipcar is piloting a Lite tier at $5 per month and a Plus tier at $19 per month, available to select members in the beta program. Zipcar accepts US licenses and most valid foreign licenses, but foreign drivers should verify state-level driving requirements before booking, as IDP rules vary by state.

How to Use a Car Rental Coupon Code

• Pick the rental brand from the GrabOn Car Rentals page and click the deal you want.
• Land on the brand site (Hertz, Avis, Enterprise, Budget, Sixt) with the deal pre-loaded, or copy the code if a pop-up appears.
• Enter pickup location, dates, and times on the rate-search form.
• Look for the box labeled CDP, Discount Code, Promo Code, Coupon Code, or Rate Code below the location field. Paste your code there.
• Click Search or Find a Car. The discounted rate appears in the results list.
• Pick your vehicle class, choose Pay Now or Pay at Counter, decline the LDW if your credit card covers it, and complete the booking.

Coupon Not Working? Here's What to Check

• Code expired. Most car rental codes last 7 to 30 days. Grab a fresh code from the GrabOn Car Rentals page.
• Wrong code box. CDP, Coupon, Promo, and Rate codes go in different fields. A CDP corporate code will not work in the Coupon box and vice versa.
• Pickup location excluded. Many codes are valid only at airport branches, only at neighborhood branches, or in specific US states. Check the fine print on the deal card.
• Length-of-rental restriction. Weekly codes need a minimum of five or seven days. Daily codes often cap at three days.
• Vehicle class restriction. Some codes apply only to midsize and above, or exclude SUVs, premium, and luxury classes.
• Blackout dates. Codes routinely block holiday weekends like Memorial Day, July 4th, Labor Day, Thanksgiving, and Christmas.
• Age restriction. Renters under 25 face young-driver surcharges of $20 to $35 per day, and some codes do not apply to under-25 bookings at all.
• Stacking conflict. Most car rental sites allow only one rate plan per booking. AAA plus a coupon code rarely stacks; the system picks the cheaper of the two.
• The loyalty rate is already lower. If your Hertz Gold or Avis Preferred member rate beats the coupon, the system defaults to the member rate, and the code looks like it failed.
• Currency or country mismatch. US codes do not work for pickup outside the 50 states and territories. Use the country-specific page for Europcar, Sixt Europe, or Hertz Canada.
• Debit card restriction. Many brands accept debit cards only with a credit check or a return flight on file. If your code is fine but the booking fails, the payment method may be the issue.

Best Time to Book a Rental Car

Cross-check the brand site against an aggregator before locking the booking. Rate parity is not guaranteed in this category.

Rental Policies and Discount Reference

About the Online Car Rental Category

The US rental car market runs through a small number of parent companies with familiar brand names underneath. Enterprise Holdings owns Enterprise, Alamo, and National. Avis Budget Group runs Avis, Budget, and Payless. Hertz operates Hertz, Dollar, and Thrifty. Independent operators like Sixt and Fox Rent A Car round out the major category.

Rentals can be booked either directly on the brand site or through aggregators like Kayak, Expedia, and Priceline that pull contracted inventory across multiple brands in one search. Pricing swings widely with airport demand, fleet supply, and seasonal travel cycles, which is why the same midsize sedan in Phoenix can cost $35 a day in January and $135 a day on July 4th weekend.

Is Booking Through Coupon Sites Worth Using?

Best for: Travelers booking three or more days, renting at airports in major US metros, and willing to compare two or three sources before clicking confirm. The Car Rentals hub on GrabOn pulls active codes from Hertz, Avis, Enterprise, Budget, Sixt, Thrifty, Dollar, and aggregator promos from Kayak and Priceline in one place.

Be careful if: you have AAA, Costco Travel, USAA, or a corporate rate code through your employer. Those rates often beat any publicly listed coupon, and most rental sites will only honor one rate plan at a time. Run the corporate or association rate first, then test a coupon, and book whichever lands lower. Also, watch out if you are under 25 - the young-driver surcharge wipes out most coupon savings unless you book through a brand that waives it.

Best saving move: Stack a corporate or association rate (AAA, Costco, or USAA) with prepaid pay-now pricing during a shoulder season window like January to early March or mid-September to early November. Decline the LDW if your credit card covers it, refuel yourself before returning, and pick up at an off-airport branch to dodge the airport facility charge. That combination routinely lands a midsize at 30 to 45% below the airport retail rate.

Explore Deals Beyond Car Rentals

If the trip needs more than just a car, browse the travel deals hub for cross-category savings, or check the flights coupons page for bundle ideas. Lodging plans can lean on hotel deals or Airbnb coupons, and aggregator search starts at the Kayak coupons page. Holiday travel windows often line up with sitewide promos at festival offers, worth a check before locking dates.
