The Darkmoon Faire is only around once a month, and the one on now is ending this Sunday, October 14th. Unless the Faire is going on, you can't trade, for example, a Crane Deck in for a Relic of Chi Ji.
Ink Vendors finally updated. Very sorry for the delay.- Greg Street (@Ghostcrawler) October 12, 2012
All these pets are bound to your account, across all servers, across both factions, and can be sold. You can log on to your level 90 main, buy some pets, learn them, then log on to another server, create a level 1 and go sell those pets at auction. All without touching the neutral auction house and its fees.
