This is what I did to level up my enchanting and to get some extra gold when farming Stratholme for Deathcharger's Reins - Item - World of Warcraft. It wasnt usefull before 3.2 patch, but now when the exploit got fixed this method can make you nice amounts of gold.
Kill all boses. I usually do only the undead side and make sure you loot all bosses. Each one drops some rares that disenchant in Large Brilliant Shard - Item - World of Warcraft, which goes for quite alot on my server, at weekends I can get 50g or more per stack of them.
Also be sure to loot ALL pieces of Twill set (Twill Vest - Item - World of Warcraft - Vest of this set) because it goes for quite alot, especialy on rp servers.
I hope this helped you to make some extra gold while farming for your mount or sword And please dont reply with all this spam comments "Common Sense", because I did like 50 Stratholme runs without looting any bosses, before I realized I could sell shards easily.
