Hey captain_hong!
Thank you for contacting us.
As Lonely_Wolf1988 suggested, you should receive email from us with the discount code in case if you did not write it down. Occasionally it may end up in your spam/junk folder so make sure you check there too!![]()
If you still cannot see it however, can you please submit a ticket by visiting our support website.
When done, please advise your ticket number and we will have a look![]()
