Rental car companies publish discounts directly on their websites. Car rental company coupon codes are also available on third-party sites including RetailMeNot and Rental Car Momma.
Budget and Avis both list coupon codes on pages named Budget Coupons at Budget.com and Deals, respectively. Many coupon codes found on car rental websites can also be located on the third-party sites, which provide coupon codes for many car rental companies in one location. Two such third-party sites are RetailMeNot and Rental Car Momma.
Clicking on coupon codes on RetailMeNot brings up a popup window listing the code with the option to copy the code and a direct link to the car rental website. RetailMeNot provides the success rate for each code, signifying the number of people who were able to obtain a discount using the code. Rental Car Momma also provides listings for coupon codes. When a user clicks on the listed coupon, a button labeled Reserve Now appears. Clicking on this link redirects users to the appropriate car rental website with the coupon code automatically inputted into the coupon code field. Rental Car Momma does not indicate if users have been able to successfully receive a discount using the available codes.
