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 different glyphs to choose from and most of them sell for quite a lot if you know how to play your cards right. Some people try to sell these items fast by pricing them low, don’t do it like that! Don’t go beyond a certain baseline that you have to establish for yourself, so you don’t end up losing money
Selling glyphs is definitely profitable, but if you want to make more money, go for the high-end glyphs such as the Northrend ones, like Icebound fortitude, glyph of chains of ice, glyph of death and decay, all of which are made from Ink of the Sea. While you’re looking into glyphs, don’t forget to check out the other ones that also sell for a good price, Glyph of Mortal Strike, Glyph of Lightwell, Glyph of Unstable Affliction, Glyph of Adrenaline rush, and many others.
In my experience, Northrend glyphs are the best way to make a lot of money. If you manage to establish a good set-up, you will be on your way to doubling your capital in no time!
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.
Making gold by selling these items in the Auction House is very easy, but don’t forget to scan AH first, before buying. Consider having a serious look at these items. I’ve already made a couple of thousands just by selling Northrend glyphs and herbs!
