As of now until all this crap is gone, I'm selling ANY leveling mat for ANY profession for 50% of the horde/alliance auction house price. I'll be willing to mail them over via neutral auction house in Stranglethorn, or trade them to you directly, or COD them to you. I do have an alt on alliance side and check prices frequently. Of course, more items = more of a discount.
Examples of mats I'm selling:
1-525 JC gems - Uncommon, Rare, Epics (Blue, Purple and Orange for now) Can also cut them into any gem you like on my Paladin.
1-525 Ore used for BS, JC and Engineering. Can prospect/smelt anything you like on my Paladin.
1-525 Inks for Inscription (including Blackfallow used for cata items/fortune cookies w. cooking) Can also make any glyph you like on my Priest.
1-525 Cooking materials (including cata fish/meat and the works) Can cook anything you like as well, since already cooked food is way more expensive then the raw food.
1-525 Enchanting materials (LOTS OF IT, including Hypnotic dust & greater celestials) Can enchant anything you like as well on my Priest.
Volatiles - Earth/Life at the moment, should be getting a crap ton of Air once I get home.
1-525 Herbs (for alchemy, inscription/milling) - Can also make any flasks/pots for you on my hunter (able to switch to pot/elixir/transmute mastery at any time). Currently potion master.
1-525 Cloth (for tailoring/bandages for them pvp'ers and what not) - LOTS of netherweave/mageweave/silk/linen/embersilk.. prob more but cannot look atm.
...And alot more. Remember, ANY item that I have currently for sale, I'm selling for 50% off YOUR faction auction house. You can pst me in game regarding stock/buying/trading, bug me in vent, or post here, and I'll get back to you in-game with your crap.
Happy Hunting! ^_^
