Missing transmog items from both NPC and/or Store

Hello,

There are missing transmog pieces to the Polar set (leather) on the Transmog NPC, and the items are even missing from Blackrock shop. However they are available in the Icecrown shop.
The items that are missing from NPC and/or shop:
Polar Boots (Leather)
Polar Chord (Leather)
Polar Leggings (Leather)

Best regards.

uhm, give me 1 reason why aren't they available? just buy it tho...

Read what I wrote again, they are not added in the NPC OR Shop. So its impossible to buy something that does not exist as for now...
