Need an Aswer from a Administrator, Thanks.

NPC - Braeg Barbarrobusta <Mercader and leather>

Summed it fast to not cause problems of understanding:

The NPC "Braeg Barbarrobusta <Mercader and leather>" (Braeg Barbarrobusta - NPC - World of Warcraft)
It does not give us the option to have (or rather, not shown)
Heavy Borean Leather x 10
(Heavy Borean Leather - Item - World of Warcraft)
arctic buying pelts
(Arctic Coat - Item - World of Warcraft 1 x 10 heavy leather borealis)

Nothing more to say for now, I hope a solution of staff or other administrative part. Thank you for reading

Regards, Rivery.

Translate please :)

Also I think you should start play english client

So from what I understand, I guess you miss Arctic fur for 10 heavy boreans at vendor. I think, it was removed from it on purpose, as many things like gems for EoH etc... So maybe you should just wait for later contents to be released and hope, they will add it back to the vendor

Yeah, that. Sorry about english.

I just want to know why i cant change on Vendor at dalaran "Braeg" 10 heavy boreans for 1 Arctic Fur. At icecrown is available... Thanks very much for the answer.

Regards, Rivery.

Probably because that option got added in on a later patch.
