Buying Dreamthistle Warhorn Skin
He’s saying he posted the offer on the BLTC. Grey market trading is trying to directly trade via mail. So that doesn’t apply to his situation at all.
Still, you’re not supposed to use these forums as a way of advertising your goods or your desire to buy. We don’t want to see this forum turn into another Spamadan, after all.
Hope you get your warhorn though, OP.
