I'm looking to get my hands on the 5 Alliance Argent Tournament pets, on my character Malcolm on Blade's Edge server. If you're interested, please post here and we can arrange to get in touch via Ventrilo or email to work out a purchase. I'm willing to pay gold or trade a Horde pet for it.
This also applies to any Horde toons currently in posession of one of the Alliance Argent Tournament pets.
Thanks for your interest!
