Can I combine loyalty rewards with other promotions or discounts?

There are no "loyalty rewards" at Guaranteed Service but there are Comfort Club Membership Benefits. Some of these benefits include a 10% discount on any service, which can be combined with any coupons. If there is a promotion being run, such as the $77 Tune-Up, the propmotion cannot be combined with any coupons.

The terms for various coupons and promotions, such as the "$50 OFF ANY SERVICE" and several other coupons specifically mention that they are non-stackable, meaning they cannot be used in conjunction with other offers[2][0][1]

You can see any available coupons on the Guaranteed Service Website.

Consider taking advantage of these valuable offers individually to maximize your benefits. To learn more about specific deals or inquire about particular services, feel free to reach out and explore current promotions independently for potential savings!
