I just completed a trade that involved store pets. Because I'm newer to the forum, and don't have as many people to vouch for me as the person I was buying the pet for, I went first. Yes, I assumed the risk, but I felt comfortable, given the person's reputation here on the forum, that it was okay.
She and I are both happy with how the trade went. But as usual, it's buyer beware.
I'd personally never use real money to buy something for someone who didn't have a high pet score, lots of posts on the forum, perhaps MVP status...some sort of permanency.
I'm certain that, if you were to get involved in one of those types of trades, you could ask the person you were thinking about trading with for references among others on the forum. It's not fool-proof, but it certainly gives a bit of peace of mind.
Thaliana#1794 - My WoW account has 50 toons, so I would so greatly appreciate people creating toons on Kael'Thas or Ghostlands to trade with me. <3
