Nothing is more frustrating than mis-clicking a vendor and buying something you didn’t intend to with your hard earned currency – and then realizing there’s no way to get a refund.

As of now, players who purchase an already-known cosmetic from the Midwinter event are unable to refund it, meaning those spent are gone for good.
