First off: It's been a long time since I contributed something so here goes!
Second: This could be common sense for most people, I'm just posting this as a tip for those who've overlooked it.
The Capitol pets you can get at the argent tournament (like Enchanted Broom - Item - World of Warcraft) are Binds when used!.
Seeing as they take a bit of time to acquire and the opposing faction doesn't have a way of getting them, I reckon they fetch a good price at the Neutral AH.
