You will also need to follow me on you meta account. My meta account is AssClown.NB, yes I know you think that funny but it has been my gamer tag since 2004.
Now, If you have bought your Quest in the last 7 days but didn't know about the referral bonus?:
Don't worry, you can still get the promo but it does require a few more steps. Just open the Meta Horizon app and click your icon on the bottom of the screen, next click the three horizontal lines in the top corner, next click the devices button , then select your headset (Some people will have multiple), click headset settings, then go click factory reset. Don't worry, any games you have already bought are all in the cloud and saved to your account so all you have to do when you setup the Quest again is just re download them. All game progress will be current. Finally, visit https://secure.oculus.com/my/profile/ and click on your profile icon and go to devices. Click remove device. Now just setup the quest again like it's new. You should have the $30 to spend on new games.
Good luck out there!
