subject: Top Five Items To Stockpile For Your Cataclysm Expansion [print this page] Infinite Dust: This item falls into the category of leveling materials that what will be required to reach the skill ups necessary for cataclysm level enchanting. I expect that they will rise in price over the course of the expansion to sit around the 4.5 wow gold mark per dust. With inflation it could get even higher and since you can occasionally find dust as cheap as 50 silver this is an easy investment with very little risk involved.
Lesser Cosmic Essences: Greater Cosmic Essences sell for about 20 gold each and their lesser cousins for approximately 9 wow gold each today. I expect these to go up to around 30 gold for greaters and 15 gold for lesser. Pure speculation based entirely on guesswork, it could turn out that infinite dust is all you need to level through the wotlk skill ups in cataclysm in which case saving these would be pointless.
Cobalt Bars: Cobalt is going to be essential for engineering and blacksmithing leveling (jewelcrafters will most likely prospect the cheaper saronite ore unless of course no one entering saronite zones in cataclysm because they stay in starter wotlk zones changes that). Having a healthy stockpile will probably net you decent returns in Cataclysm and if you asked me to guess. Oh you are asking me? Ok well in my humble and experienced opinion cobalt bars will sit around 50 gold per stack in the expansion.
Alchemy Leveling Kits: Ok so this really is a collection of items but the idea is that you gather all the materials needed to powerlevel someone from 1 to 450 alchemy and you sell it. The only problem is that leveling requirements and recipes could change drastically in cataclysm. Theres no guarantee that your stockpile will even work! However, the rewards for doing this are massive, in saving someone the time to gather the materials themselves they will often be willing to pay thousands of world of warcraft gold more than the items are worth as a whole. Ive sold alchemy and blacksmithing kits for 4k profit and come cataclysm I wouldnt be surprised to see kits worth 2.5k going for 7-8k gold easily.
Borean Leather: This is an item Ive not seen anyone talk about when preparing for cataclysm. Thats a good thing too for people wise enough to start stockpiling it today as I predict prices for borean leather will reach the 35-55 world of warcraft gold mark per stack during the expansion. Right now it goes for about 20 gold a stack so thats a pretty nice profit margin if Im right! No matter what the price should remain as high as it is today so you will at worst break even or at best double your money.
