Cut Your Rentcars Total Today

Say you’ve got a week-long trip and you’re hunting for a compact car in Miami. Before you hit “Book,” here’s where the real savings come from at Rentcars.

• Sign up and save $20 on your first booking. New accounts get a flat $20 off with no minimum cart value. If your rental runs $60-$80, that’s a 25-33% discount on the first trip alone. Create an account before you search.
• Newsletter promo codes land before they go public. Rentcars emails exclusive discount codes to subscribers, sometimes 10-15% off, that don’t show on the main site. Subscribe before a planned trip rather than the week of.
• Compare across 300+ rental companies in one search. Rentcars aggregates rates from brands including Hertz, Avis, Budget, Europcar, and local operators. The same car class at the same airport often shows a $15-$30 per-day spread. That’s not a coupon, but it’s the biggest lever.
• Book at least 7 days out for the best rate. Same-week bookings on Rentcars tend to run 20-30% higher than rates locked in a week or more ahead. The platform’s pricing model rewards early reservations.
• Earn 10% cashback on qualifying bookings. Rentcars runs a digital-wallet cashback program that credits 10% of your rental cost toward the next booking. Good for anyone who rents more than once a year.
• Check GrabOn before every reservation. GrabOn lists verified Rentcars promo codes, updated daily. The sitewide percentage-off codes (currently up to 40% off) apply to most destinations and car classes.

Apply a Rentcars Coupon Code in Seconds

1. Go to GrabOn’s Rentcars page and click the offer you want. The deal opens on Rentcars automatically.
2. On Rentcars, enter your pickup location, dates, and car class. Click “Search.”
3. Choose your car from the results. Click “Book” or “Select.”
4. On the booking summary page, find the “Coupon” or “Promo code” field. Paste your code there.
5. Click “Apply.” Confirm the discount shows in the price breakdown before entering payment details and completing the reservation.

Fix a Rentcars Promo Code That Fails

• Minimum cart value not met. Some Rentcars codes activate only above a threshold. Fix: Check the offer terms on the GrabOn coupon card before applying.
• Code already used. Rentcars discount codes are usually one per account. Fix: Log out, check if the code works on a different account, or grab a fresh code from GrabOn.
• New-user restriction. The $20 signup discount and certain percentage codes are for first bookings only. Fix: The code will not fire on existing accounts with prior orders.
• Destination exclusion. Some Rentcars promo codes apply to specific countries or regions only. Fix: Read the coupon’s terms for geographic restrictions before searching.
• Expired code. Rentcars codes often expire within a few days of going live. Fix: Grab a current code from GrabOn, which updates listings daily.
• Code entered in the wrong field. The promo field only appears on the booking summary screen, not the search results page. Fix: Proceed through to the booking summary before looking for the code input.
• Case-sensitive entry. Rentcars codes are typically uppercase. Fix: Copy-paste from GrabOn rather than typing manually.
• Payment method mismatch. Certain Rakuten or Capital One Shopping rebates require the respective browser extension or card active during checkout. Fix: Activate the extension before starting your search.
• Car class excluded. Luxury and specialty vehicles sometimes fall outside the scope of general discount codes. Fix: Try the code on a standard or compact selection first.
• Klarna or BNPL conflict. Some split-pay methods do not stack with a coupon discount on the same booking. Fix: Pay in full to use the promo code, or forgo the code and use BNPL.

Rentcars Coupon Terms Explained

• Promo code / coupon code: An alphanumeric string you enter at checkout to reduce the booking price. Rentcars accepts one code per reservation.
• Minimum order value: The lowest booking total a code will activate on. Rentcars sitewide codes often have no minimum; destination specials sometimes require a $30-$45 base fare.
• One-per-account: Most signup and first-order codes fire once. Attempting them on an existing account returns an error.
• Sitewide vs. category: Sitewide codes apply to any car class and destination. Category codes may apply only to, say, “compact” or “SUV” cars at airport locations.
• Auto-applied deal: No code needed. The discount appears automatically when you click through GrabOn’s offer link.
• Cashback offer: A credit returned to your Rentcars digital wallet after the booking is completed. Not a direct checkout discount.
• Verified offer: GrabOn staff have confirmed the code or deal is active. Verified badges on the listing mean the offer worked within the last 24 hours.

Rentcars Bank, Card and Payment Offers

Bank or Method	Offer	When and How
Rakuten	Variable cashback on Rentcars bookings (rate changes seasonally)	Activate Rakuten browser extension before searching. Cashback posts after the rental completes.

Credit cards (Visa, Mastercard, Amex)	Standard checkout payment. Some travel cards offer rental insurance as a cardholder benefit.	Pay online at checkout. Check your card’s travel benefits guide for complimentary rental coverage.
PayPal	Accepted for prepaid online bookings	Select PayPal at the payment screen. Prepaid bookings typically return a lower rate than pay-on-arrival.

Debit cards may not be accepted for pay-now reservations at all rental companies in the Rentcars network. Confirm payment eligibility with the specific rental partner shown in your results before booking.

Rentcars First Booking Guide

New to Rentcars? The $20 first-order discount is the best single saving available on the platform for new accounts. Here is how to claim it.

1. Go to Rentcars.com and click “Sign Up” in the top menu.
2. Create an account using your email or a social login.
3. Search for your rental by entering pickup location, dates, and car class.
4. Select a car and proceed to the booking summary. The $20 discount applies automatically at this screen for new accounts.

The offer has no minimum booking value. Even a $39-per-day compact rental qualifies. Note that the discount applies to the base rental price, not to optional add-ons like GPS or child seats that some rental partners charge separately.

Rentcars Programs Worth Joining

Rentcars Cashback Wallet

Every completed booking through Rentcars earns 10% of the booking value back as wallet credit. The credit applies to your next reservation, with no minimum. For a traveler who rents a car 3-4 times a year, the wallet balance can cover a significant portion of one trip. Credits do not expire while your account is active, but check the terms if you go more than 12 months between rentals.

Affiliate Program

Rentcars runs an affiliate program that pays up to 50% commission on completed bookings. If you write a travel blog or manage a social audience, the referral earnings can offset your own rental costs. Sign up through the Rentcars website under “Partners.”

Rentcars Mobile App

The Rentcars iOS and Android app lets you search, compare, and manage bookings on the go. Some app-exclusive rates appear after logging in that differ from the desktop results. The app also stores booking confirmation details offline, which matters when you land at an airport without a reliable data connection.

Return a Rentcars Order the Easy Way

Cancellation rules at Rentcars depend on when you cancel relative to the pickup date. If you cancel before the pickup date, Rentcars charges a 5% administrative fee on the total amount paid. That is lower than many car rental platforms, which charge a flat first-day fee or forfeit the full prepayment.

Cancel after the pickup date and you are charged an amount equivalent to one day’s rental rate. For a $20-per-day compact car, that’s $20 out of pocket if you cancel on the day of pickup. It is worth knowing this before booking a non-refundable rate that saves $5-$8 over the flexible option, since the math rarely works in your favor.

For the latest cancellation terms specific to your booking and rental partner, review the policy shown on your booking confirmation email or the Rentcars help center before your travel date.

Stores Worth Checking Before You Buy

Discover Cars is a car rental aggregator that covers 145 countries and lists rates from both global chains and local operators. Their “Full Coverage” protection option bundles insurance into the rental price, which simplifies the process for travelers who want one flat cost. GrabOn has verified Discover Cars coupon codes if you want to compare rates before committing.

EconomyBookings focuses on budget-conscious renters and frequently shows rates that undercut the major brands on short city-center rentals. Their comparison tool covers 30,000+ locations globally. Check GrabOn for current EconomyBookings promo codes before booking, particularly for European and Caribbean destinations where they tend to show the sharpest prices.

The Rentcars Sale Calendar Worth Knowing

Car rental prices on aggregator platforms like Rentcars move daily based on inventory and demand. A few patterns hold year over year.

Sale Name	When It Happens	What to Expect
Black Friday Sale	Late November	Rentcars has run promotional codes exclusively for newsletter subscribers during Black Friday. Savings of 20-30% on select destinations. Subscribe ahead of time.
Cyber Monday	Monday after Thanksgiving	Site-wide promotional codes tend to appear on Cyber Monday for online-only bookings. Check GrabOn that day for active codes.
Summer Peak Avoidance	Book in April-May for June-August travel	Car rental inventory drops fast from Memorial Day onward. Booking 6-8 weeks out for summer trips locks in rates that are 20-35% lower than last-minute.
Labor Day Weekend Deals	Late August	Some rental partners reduce rates for the last summer hurrah. Compact and economy classes typically show the deepest cuts.
New Year / Post-Holiday Clearance	January	January is historically the cheapest month to rent a car in the US. Demand falls sharply after the holidays and rates follow.

For current promotional codes on any of these events, check GrabOn’s Rentcars page before your travel date.

Rentcars at a Glance

Rentcars was founded in 2009 in Curitiba, Brazil, by Francisco Millarch and Viviane Montanari. It started as a car rental comparison tool focused on South America and grew into the largest online car rental platform in Latin America. Today it operates in 160+ countries and aggregates pricing from more than 300 rental companies, including global brands and regional operators that rarely surface on mainstream travel sites.

The platform competes directly with Discover Cars, EconomyBookings, and QEEQ on price aggregation. Its primary edge is the depth of Latin American inventory and the ability to compare pay-now versus pay-on-arrival pricing side by side. Trustpilot shows over 144,000 reviews with a 4.5/5 average rating as of mid-2026.

Rentcars: The Honest Verdict

Best for: Travelers comparing car rental prices across multiple companies without visiting each site individually, especially for Latin American destinations or trips where local operators offer better rates than Hertz or Avis. The $20 new-user discount and 10% wallet cashback make it worth a look even for North American and European rentals.

Be careful if: You need a car on zero notice. Last-minute inventory on Rentcars can be thin, and the 5% cancellation fee means locking in a booking speculatively costs you something. Also worth knowing: Rentcars is a comparison and booking platform, not the rental company itself. If something goes wrong at the counter, you are dealing with the rental partner directly, not Rentcars customer support.

Best saving move: Book 7+ days in advance, apply a GrabOn Rentcars coupon code at checkout, then activate Rakuten in your browser for cashback on top. That combination can cut a $200 weekly rental to under $150 in favorable inventory conditions.
