You had a offer on 20-22.4 for the following "Buy 3 games and get 10$ credit and 1 months subscription to Viveport". It said that the codes would be sent after 22.4. I have not yet received mine.
So far the experiences with Vive site hasn`t been that promising, and if I read the support forum and people experiences about Vive warranty and repairs, I would have never bought HTC Vive.
The codes are being emailed later today.
