How it works

This is what Meta's mobile app says:

This means that when you use one of the codes on this website, Meta will give you 25% off your game, and will give me 5$ store credit :)

Or, if you are buying a new VR Headset (From meta) and use the link, you will get 30$ free, store credit, to buy some fun apps and games for your new headset.

So there is no reason I can think of not to use a referral code when buying a VR game, because who wants to pay that extra 25% when they don't have to?
