Taxes and non-optional fees don’t earn points, so via the promotion this booking would earn 788 Gold Rewards points. That’s more than enough for a free rental day for a non-premium car.Using the double rewards promo code, the price for that same booking fell byBefore members complete their reservations, they must select “Earn Hertz Gold Plus Rewards Points” within the section titled “Arrival/Flight Information.“Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
