I stopped trading in 2017, but now I am intrigued if steam still has the same rule.
The last thing i remember is that the only games one could store in the inventory were the additional gifts of 4packs, but all the others could only be sent to a friend directly (who can accept it to library or reject it and be refunded). Is it still the same?
And that leads me to another question: Do new gifts here on dispenser get placed regularly, or is there a limited ammount of games that will only decrease with time until none is left?
