The eternal struggle for most World of Warcraft players is trying to find enough gold in order to enjoy the game at its maximum level. Notice how I said most players. There are a small group of players who generate large profits every day from the auction house and the trade channel. The basic concept is pretty simple: buy low and sell high.
You've no doubt seen someone selling multiple epic items on the trade channel, and no doubt you've often wondered how a player can accumulate so many epic items when the drop rate for some items require over a 100,000 mob kills? That player is one of two potential players: the bank manager for a large raiding guild or she is a reseller.
Large raiding guilds will find bind on equip epics every day, especially if they're raiding one or more instances on a daily basis. The odds are in their favor for finding epic quality items since they have a large group of organized players that can routinely clear end game instances. Usually once a week, the guild's bank manager will sell the epic items the guild doesn't need.
