There is an existing thread
here but unfortunately not very up to date.
There is a current promo ex-EU for the US but it is a personal code and I have used mine. Maybe someone else who is not planning to use theirs will post it for you.
I have found this forum often unhelpful when it comes to disclose this type of information. They hold the moral high ground that if you have not received the code then you are not entitled to it. I will happily post any generic code I receive and any one-off codes that I am not planning to use.
Good luck with your quest and have fun in LAS.
