A huge money making opportunity came out when Wrath of the Lich King expansion was released, one of these involves selling glyphs.

There are a lot of glyphs to look into, and most of them sell for a good price. All you need is a bit of knowledge about them, and to be business wise.

People are not entirely sure about the prices yet, but don't follow their examples if they are selling for way too low!

Even the most common glyphs can sell for a good pricem but if you really want to make tons of gold within a reasonable amount of time, you should look into the Northrend glyphs.

For example, you should consider the glyphs of death and decay, Icebound fortitude, Chains of Ice, and Molten Armor. These are glyphs made from Ink of the sea, and they sell for a lot!

You can also have a look at other glyphs such as Glyph of Lightwell, Glyph of Unstable affliction, Glyph of Mortal Strike, Glyph of Adrenaline rush, and so forth.

Northrend glyphs are actually the best way to go, they are the high-end part of the glyphs market, and if you manage to create a considerable pipeline through these glyphs, you will be able to double your capital within a couple of days to a week. Northrend glyphs easily sell for 20 gold minimum! You can easily make thousands of gold a day if you play your cards right.

A huge demand for herbs is also a result of the release of Wrath of the Lich King. People are generally looking to buy things for inscription. If you decide to sell herbs, go for the high-end ones as usual, herbs like Deadnettle, Goldclover and Tiger Lily are going for a lot in most servers. Don't forget to look into other herbs such as Adder's tongue, Icethorn, Frozen Herb, Lich Bloom and Frost Lotus.

You will make a lot of gold from selling these herbs at the Auction house. Ive seen these going for a lot, so consider looking into these items mentioned here and start making money.
