Runway Discount ("Runway" or the "Company") is a privately held online retailer that sells discounted high-end fashion. In an effort to increase its sales and customer base, Runway implemented a customer referral marketing campaign (the "Refer-a-Friend Program") whereby existing customers can refer friends to Runway and receive a $25 credit towards the purchase of future merchandise. The terms of the program are as follows:

Runway offers existing customers (the "Existing Customer") a $25 credit (the "$25 Referral Credit") if the Existing Customer refers a friend (the "New Customer") to Runway's Web site and the New Customer purchases merchandise from Runway. After a purchase is made by the New Customer, the Existing Customer receives a$25 credit to be applied to a future purchase from Runway.

The $25 Referral Credit represents the fair value of the cost Runway would pay to acquire a new customer from an unrelated third party or marketing firm who is not a purchaser of its products. The program is open to all of Runway's customers and does not need to be combined with any initial or existing purchases.
