CheapOair购买机票后返现怎么操作？
请教哦：今天在cheapoair上订了票，然后邮箱的确认邮件中有一段提示:
Click here to claim your $40 rebate on the reservation you just made.
Billing terms and conditions apply.
claim your cash back with enrollment in Great Fun.
请问这是返现吗？
我点击后出来一个页面，提示以下内容：
limited time offer from a preferred partner of Cheapoair.
$40 cash back rebate on today's Cheapoair reservation when you try Great Fun.
Call now for your $40 cash back rebate off the reservation you just made!
1-888-****(一串电话号码)
Billing term & conditions apply. Limit one per household. Call now toll free.
我的英文很烂，用百度翻译试着看了下，但第一次在cheapoair订票，不懂我是否可以有反现，该如何操作？
特别请教下，非常感谢！！！
