Crafting, Convenience, and Capitalism

Every WoW player should try, at least once in their playing career, selling [Ice Cold Milk] on the Auction House during the Christmas Event where you can often get up to 1g per piece. You can buy it from a vendor in unlimited supplies for 25c (1.25s for 5 pieces) literally 5s walk away from the Auction House.

You will learn a lot about the nature of people, consumers, and trade by making that one transaction.
