As a result of taking advantage of preorder offers (and also a result of Telltale Games' copious generosity), I have multiple serial numbers for some games. I have three copies of S&M: Ice Station Santa and two copies of S&M: Culture Shock. That's three more serials than I logically need to have.
What I'd like to do with those additional serials is gift 'em to someone. Is it possible to do this? If so, how?
