Tired of sitting in a big city looking for trades all day long? Luckily you don't have to. With this trick you can watch for good deals while grinding mobs or doing quests.
How to trade while questing:

1. Have an alt character in the city you want to trade in. This character will handle the trades.

2. Create a new chat window and join the trade channel of the city you want to trade in. For example: "Trade - Orgrimmar"

3. Now you can do what ever you want. Go questing, grinding mobs or what ever. Keep an eye on the trade channel for good deals.

4. Found something being sold for a good price? Now just switch to your alt character, go buy the item and mail it to where ever you need it.

Remember to use Auctioneer so that you'll have a better grasp on prices of the different items people are selling on the trade channels.
