Anyways, I have the pet's key and I'm looking to sell it for in-game gold because that's a tad more more useful to me. I'm taking offers for it now - note that normally, you can buy it from the Blizzard store for $30.
Minimum asking price: 8k gold. If I get an offer above that, I'll post that amount on here.
Edit: The pet has found a new home! Thank you for all your responses!
