As the majority of Invadedlands knows, chargebacks occur a lot; and majority of them are from irl deals. As awesome as I am, I thought of a way this can be avoided:
A GUI which allows player1 (who offers in game items) to trade with player2 (who offers from the store). Player1 will put the in-game items in one half of the trade gui, while Player2 will be able to put a package of the store-bought item. Similar to the /trade.
