Pilgrim's Bounty is here again. This provides a few opportunities for players to make some extra gold. Mages in particular will be able to make gold selling ports to the major cities. The dailies for this world event require each player to complete a quest in each city every day. There will be plenty of players willing to pay mages for their portals.
Another opportunity to make gold is by selling Tracker Snacks. As I pointed out in an earlier post Planning For Success these are made using Shoveltusk Flanks and Northern Spices. Tracker Snacks are helpful in completing the quest The Turkinator. This is one of the more difficult quests needed to complete the meta-achievement to get the holiday pet Turkey Cage.
You can also make money selling Wild Turkeys to other players for their daily quests. These are obtained by killing turkeys in Elwynn Forest or Tirisfal Glades. While these cannot be listed on the auction house they can be traded so be sure to advertise in chat.
Another possibility lies in cooking. This holiday provides players to level their cooking from 1-300 in a very short time using the recipes available from the quest giver in the Bountiful Cookbook. After this players must level their cooking on their own. If your server permits you might try cornering the market on Outlands and Wrath level meat used for cooking.
Be sure to check out WoW Insiders Guide to Pilgrim's Bounty 2011 for details on all the quests.
