i played TWD and got really into the adventure game genre. Now i am interested in buying the "The Walking Dead and the Almost Everything Pack", but i already own a digital copy of "The Walking Dead".
So is it somehow possible to upgrade my order from "The Walking Dead (24.99$)" to "The Walking Dead and the Almost Everything Pack(44.99$)" by just paying the price difference (20$). Or is it possible to get a gift coupon with the value of 20$ for further purchases.
If neither is possible, what are my options with a second digitial copy of TWD? Can i sell it somehow?
I hope any staff can answer my question.
