From the guide:
"In this section you will find all the recipes that a Horde character can purchase from a vendor, or NPC. It tells you the locations of the vendor, the name of the vendor, how much the recipe will cost you when buying it from the vendor, and the suggested auction house buyout price for that item. If an item is a limited supply item, it means that the vendor has a limited quantity of that item, usually only 1, at a time. The item will regenerate after a while. So if a vendor doesn’t have a limited supply item that this guide says they should have, it just means someone has bought it recently and it has not regenerated yet. Also, please remember that every single server’s economy is different and there is really no set it stone buyout price you should use. Mainly, use the suggested price as more of a guideline more than anything else, and then see what that item is selling for on your server at that time. Also, do not flood the market with these recipes. List only one or two of each recipe at one time. This keeps the demand stable for the item."
Hope this will be usefull for you guys.
