Despite how far the Oculus Rift’s price has come down since launch, for many potential buyers it’s still a little too expensive to justify. If you’re an owner, you’ll often find yourself wishing that your friends had one too so you could play co-op and multiplayer VR games together. Games like Raw Data, Arizona Sunshine, From Other Suns, and Echo VR are much better with friends.

Well, we have good news for you. Earlier this month, Oculus launched a referral program for the Rift, seemingly intended for this exact scenario. By referring your friend to purchase the Oculus Rift, your friend gets 10% (around $40) off the Rift, and 30 days later you receive a $30 Oculus Store credit for VR apps/games.

Of course, there are some restrictions here. For starters, it’s seemingly USA-only for now, so both you and your friend will need to be in the USA. Additionally, each Rift owner can only refer up to 3 friends, however technically those friends could refer even more.

Oculus CTO John Carmack recently stated that the Oculus Go headset was beating sales expectations, but no similar statement has ever been made about the higher end Rift, and many analysts believe that the Rift (and PC VR in general) is selling poorer than many expected. While $40 off doesn’t make a radical shift in affordability, it may be just what’s needed to get some people to join their friends in PC VR, a natural way to grow the Rift user-base.
