I have made a few trades via deckbox in person and through mail but I do tend to trade more using MTG Market Australia and Sydney MTG Traders through the name Matthew Liu. I usually send the cards the day after the trade is confirmed in a bubble envolope and toploader. I also do meet ups at GGHurstville and SOMETIMES although very rarely at GG Central. Most of my cards are for trade, I will also listen to offers and if the price is right I am open to trading anything.
