As it’s Christmas…
Is there a way to buy other users Gift Vouchers for the Marketplace at all? If not, could there be :)?
That actually is a nice idea… 
This was semi-raised when UE4 was still paid. I don’t have the post at hand
This is a feature that Unity Asset Store has. You can generate 12 vouchers a year per asset in the store. It’s useful for marketing and reviews. It’d be a great feature to have for asset developers.
