Chance to make Cash??Follow

Hi was just wondering, what do you guys think might be some good items to stock up for TBC? With new items and stuff coming out, certain things might have an increase in value so this might be a good time to make some cash by stocking up on them while they are cheaper. Also, what are some items that may dip in prices? Heard that essences might not be a good choice as there are so called "higher level" items such as mode of (element) and primal (element) coming out.

If you have mining, save ALL THE GEMS YOU CAN GET. I'm gussing at least 1/7 of the WoW population is going to switch to Jewelcrafting, so there's going to be a lot of price gouging on precious jewels.

I was told to save gems and pally gear (being horde) until the expansion, but have second thoughts on both. I'm not going to waste my time, gold or space personally.

There are some world drop blues that are only useful for pallies or shammies so I would save those if they drop and sell them for a lot when TBC comes out. The new characters will want to have uber gear as quick as possible.
