- Coupons are built in: Avis, Budget, Hertz, Dollar, Thrifty, and more all have coupons and discounts applied automatically when you search. Just enter your dates and location and Smart Book does the rest.
- Stack coupons with discounts: Many agencies allow a coupon and a discount code to be combined on the same booking — our engine applies both simultaneously where valid. See our individual agency pages for details on stacking.
- Free upgrade coupons: Some free upgrade coupons are applied automatically and appear in search results (Avis, Budget). Others are applied at the counter — we mark these with a (c) in the description.
- BCD codes (Budget): A BCD (Budget Customer Discount) code is Budget's discount program — similar to an AWD at Avis or a CDP at Hertz. Several are built into our Budget page and applied automatically.

- Most coupons are publicly available — no membership required unless stated on the individual offer.
