Snatch List

As well as Obsidium Ore on your snatch/search list, you should add the following:

Cut Hessonites, Zephyrites and Alicites for less than 9g
Stacks of bandages under vendor prices
Frozen Orbs Under 5g – Dont vendor these, trade them in Dalaran for Arctic Fur or Eternal Fire depending on the prices and supply. <-still works in 2016!
Primal Nether
High Level Scroll of Enchant and other cataclysm crafted items selling for under their mats prices. Hoard these for later in the expansion.
