Cost = materials at today's floor (v = not on the AH, priced at the vendor). Sells for = the crafted item's floor after the 5% cut. Gold/day = profit × how many sold per day lately (capped at 20): what you could make if you kept the market supplied. Recipes that make nothing sellable (most enchants) aren't listed.
