[Expired] New Amex Offer: Save $100 on Your Next Hertz Rental [Until October 31]

Renting a car can be expensive, but there’s a new Amex Offer that will save you $100 on any Hertz rental that costs $500 or more — or multiple rentals that add up to that amount.

This can provide considerable savings, though there is a drawback to using an American Express card to rent a vehicle, which we’ll get into below.

Hertz Amex Offer Details

This new Amex Offer expires on October 31, 2025, and requires you to spend at least $500 with Hertz to get a one-time $100 statement credit. With Amex Offers, you can spend in multiple transactions, so you don’t necessarily need to spend $500 all at once.

However, you do need to add this offer to your card by September 30.

Unfortunately, Amex cards don’t typically come with primary rental car insurance, so if you add on Amex Premium Protection, this will be an extra cost of $12.25 to $24.95 for each rental period, potentially negating any savings. You should calculate the costs to determine which option is most cost-effective for you.

Your rental must be from a Hertz corporately owned location in the U.S. (such as an airport location). The rental has to be paid by October 31, 2025, so plan to return several days prior, leaving plenty of time for the charge to post onto your card — assuming you didn’t prepay in full at the time of booking.

Additionally, you need to make your reservation directly with Hertz instead of another website or third party. Lastly, this offer doesn’t cover incidentals like tolls or Rent2Buy offers.

About Amex Offers

Amex Offers provide a statement credit or bonus points after spending with an eligible merchant. However, you need to add the offer to your card before making a purchase and must complete the spending by the deadline listed in the offer. Additionally, you need to ensure you use the card that you added the offer to, because using a different card for payment won’t trigger the offer.

Each card in your account may be targeted for different stores or amounts, so you’ll want to scroll through all of your cards to see what you’re eligible for or which card may be best for the savings. Then, add the offer to your card before spending.

Final Thoughts

With the cost of rental cars these days, this is a timely offer to save $100 on your next set of Hertz rentals totaling $500 or more.

See if it makes sense to charge your rental to your American Express card or if charging to a different card that provides primary rental car protection would be better.
