# Coupons Tab
The coupons tab allows you to offer discounts to your customers through coupon codes that you supply to customers. Up to five coupons may be set up per program. If you enter multiple coupon codes they must be unique. Enter the amount or percentage (e.g. 10 for 10%) but not both as only one will be used. To turn off a coupon just make it inactive or change the dates. Coupons are not ‘stackable’ as only one coupon will be allowed per registration. Coupons that cover 100% of the cost are not supported.
The picture below shows what it will look like on the registration page of your event if you have coupons available.
