我发Email问wowvps的优惠码是否终身有效并且可以多次使用，他们的回信如下：
There is no expiry day currently and the coupon is good for the life of the account.   If you sign up with the coupon, it will be the plan and price of your account from the day you order and for every invoice afterwards regardless of if the coupon was to expire at some point.

请帮我翻译一下回信，谢谢。

目前優惠碼是無限期的   
如果購買時用了coupon，以後也是同樣的，不會改變
