I never had much luck in the Auction House until I got high enough in fishing to catch firefins and oily fish. A full stack of those sells for several gold and has allowed me to go from having an average bank account of 50-75 silver to 10 or more gold at any given time. One hour of fishing in Southshore nets me about 10 gold at the AH. I know in the grand scheme of things 10G is nothing but for me it is opening a lot of possibilities (not to mention making keeping my Paladin well armed and armored possible.) I am leaving the weapon and armor selling to my wife since she has infinately more luck selling those than I do. I can't wait to go fish higher level areas. So... how do you make your money?
