At the Auto Sentry, if customer is using a Coupon Code, the customer must enter the Coupon Code which is initiated by selecting the Enter Coupon button.  When the coupon is entered it will be validated against the Coupon profile to ensure it is valid and enabled at the time of entry.  If it is proven to be valid, the words Discount Coupon will be displayed beneath the video window and the wash selections appear on the screen. When a base wash is selected, the discount name and amount will be displayed on the on-screen receipt along with the base wash name and amount.

NOTE: Percentage discounts will only be applied to the selected Base service but not the extra service.
