Sers,
here a good Scam that worked for me:
You need a Book of Glyph Mastery and several Arcane Tomes (those books from scryer reputation). Go to your Trade-Chan and offer Book of Glyph Mastery for a good price on your server. When someone wants to trade, put the Book of Glyph Mastery in the first Slot and after a few seconds befor he accepts (while he enters the amount) switch it with the Arcane Tome which looks identically.
