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 return 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 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.

How to Use a Car Rental Coupon Code

1. Pick the rental brand from the GrabOn Car Rentals page and click the deal you want.
2. Land on the brand site (Hertz, Avis, Enterprise, Budget, Sixt) with the deal pre-loaded, or copy the code if a popup appears.
3. Enter pickup location, dates, and times on the rate-search form.
4. Look for the box labeled CDP, Discount Code, Promo Code, Coupon Code, or Rate Code below the location field. Paste your code there.
5. Click Search or Find a Car. The discounted rate appears in the results list.
6. 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.
• Loyalty rate 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 booking fails, the payment method may be the issue.

Best Time to Book a Rental Car

Pricing on rental cars moves fast, and the cheapest window varies by city and season. Here is the rough calendar.

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, Fox Rent A Car, and Europcar (mostly through US partner branches) round out the shortlist.

Rentals book either direct on the brand site or through aggregators like Kayak, Expedia, and Priceline that pull contracted inventory across multiple brands in one search. Peer-to-peer alternatives like Turo, Zipcar (hourly), and Getaround sit alongside the traditional category for shorter trips and city use. Pricing in the segment 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.

Deals From Similar Stores

Hertz coupons bundle Gold Plus Rewards member rates with weekly promo codes that stack on midsize and above. The brand runs frequent free-upgrade weekends and is the leanest option for one-way rentals between major airports. Skip-the-counter access works at most US airports for Gold members.

Europcar coupons matter for travelers heading abroad or driving into Mexico and Canada from a US start. Europcar's network covers more than 130 countries and the codes work across the partner brands for cross-border bookings. Worth a check before defaulting to a US-only brand for an international trip.

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 careful if you are under 25, the young-driver surcharge wipes out most coupon savings unless you book through a brand that waives it (USAA does for active military).

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 return, and pick up at an off-airport branch to dodge the airport facility charge. That combination routinely lands a midsize at 30 to 45 percent below the airport retail rate.

Car Rental FAQs

How much can car rental coupons actually save?

Car rental coupons typically save 10 to 30 percent off the base rate, with the deepest cuts on midsize and above during shoulder seasons. Coupon codes do not reduce taxes, airport facility charges, or young-driver surcharges, which can together add 25 to 40 percent on top of the base rate. The actual dollar savings range from $15 on a two-day economy to $80 or more on a week-long SUV. Stacking a corporate rate (AAA or Costco) with prepaid pricing usually beats a coupon on weekly bookings.

Which car rental brand has the best coupons?

Budget and Hertz publish the most aggressive coupon codes month to month, typically 20 to 25 percent off, while Avis and Enterprise lean on free-upgrade promos and association rates instead. Sixt runs fewer codes but tends to price lower at large airports out of the gate. National skews toward Emerald Club member rates over public coupons, so the program is worth signing up for if you rent often. The right answer depends on the city, the rental length, and whether your card or membership unlocks a better rate.

Is it cheaper to book a rental car directly or through Kayak or Priceline?

Aggregators like Kayak, Priceline, and Expedia often surface a lower base rate than the brand site, but the brand site usually wins once loyalty member rates are applied. Run both. Aggregators pull contracted inventory and bundle codes that direct sites do not show, while brand sites surface member rates and free-upgrade promos that do not appear on aggregator results. Pay-now prepaid pricing on Priceline can also undercut both, with the tradeoff that the booking is non-refundable.

Do I need to buy the rental company's insurance?

Most US credit cards (Capital One Venture, Chase Sapphire, Amex Platinum, Citi Premier) include collision damage coverage when you pay for the rental with that card and decline the rental company LDW. Verify with your card issuer before the trip because primary versus secondary coverage matters. Personal auto insurance also extends to rental cars in most states. Skipping the LDW saves $20 to $35 a day, which usually exceeds the value of any coupon code.

Can I rent a car with a debit card?

Most major brands accept debit cards at pickup, but with conditions like a credit check, a return flight on file, or a higher hold amount. Hertz, Avis, and Enterprise allow debit at the counter under those conditions. Budget and Dollar are stricter. Prepaying with a debit card online and then collecting at the counter is usually the smoother path. Bring a second form of payment in case the hold is rejected.

Is there a young-driver surcharge for under-25 renters?

Yes, renters aged 21 to 24 pay a young-driver surcharge of $20 to $35 per day at every major US brand, and most brands do not rent to under-21 outside of New York and Michigan, where state law requires it. USAA waives the surcharge for active-duty military. Costco Travel sometimes negotiates a lower surcharge through partner brands. Coupon codes rarely apply to under-25 rentals, so factor the surcharge into the actual booking total before assuming a code will close the gap.

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.
