My friend has just sent me a gift for Christmas on Steam, but I already have a copy of it.
I want to know what will happen if I decline the gift. Will my friend be able to get a refund on it, or will he just have the game himself?
A declined gift will be returned to the owner’s gift inventory, from where it can be gifted again.
Valve generally does not grant refunds in this case, as Steam already tells the user if the gift target already owns the game.
