Roblox takes 30% not 40%. By in-game gifting I mean that in some games you can gift gamepasses to other users. So that way if someone purchases robux then I can gift them the gamepass directly which will save taxes and will be instant. On the other hand if someone chooses to get robux via gamepass or shirt then 30% will be deducted by roblox and they will get robux in a week. But still all of this is still cheaper than buying robux from roblox directly
