To take advantage of this World of Warcraft strategy you will need an enchanting skill of 275. This could save you some serious time from wow gold farming.

Head to the nearest auction house and do a search for level 65-70 uncommon items. Purchase every green item that is priced at less than 5 gold, then head to the mailbox and pick up your purchases. Disenchant the items you have purchased.

You will most likely get a few Arcane Dusts or a few Greater Planar Essences. The Arcane Dust will sell on average for about 2 gold each and the Greater Planar Essence will sell for 4 gold each.

You can also do this trick with level 65-70 rare items. Purchase any blue item that is priced a less than 20 gold. Follow the same steps as above. The items will more than likely disenchant into Large Prismatic Shards that sell for around 25 gold each.

Remember that every realm will have different economics, so the prices and values of individual items may vary.
