Note that it takes about 4 hours for the promotion to be activated.4.giveaway的discount to entrants促銷設置需要注意以下幾點：(1)該促銷是針對參加giveaway但是未獲獎的參與者有效(2)設置好的促銷的折扣需要在10%到40%之間，且在接下來的9天內都要是active 的狀態(tài)(3)促銷需要選擇Single-use的促銷碼參考頁面：https://www.amazon.com/b/?encoding=UTF8&node=11715260011此外，對于添加到giveaway的促銷，除了保證后臺是active之外，還需要保證促銷的截止時間必須是晚于giveaway的截止時間，即賣家的促銷時間必須包含giveaway的整個時間，即整個giveaway持續(xù)的時候，促銷必須是正常有效的，故active的促銷并且起止時間需要包含giveaway的起止時間。
