WTB Essence of winter or frost temper - Also need info on Essence drops

[BarackObooma]

I would like to buy a bunch of essence of winter or frost temper to work on my barbarian cultural armor. Please send me a message in or out of game with price.

Also

Does anyone know the best place to farm essence of winter?

The wiki says that ice giants (in Everfrost) drop it but after killing several, I didn't see any. I talked to a druid that farms IGs regularly and they said they've never gotten any.

The only other thing listed in the wiki that could be soloed are tundra yetis in Dreadlands. Can anyone confirm if they do drop regularly from them or if there is a better spot?

Thank you,
